I know this video is about 2 years old but I’m new to the channel. I’ve had 2 WJ’s. They are great but have their quarks. I’ve done all the conversions you have, just with different companies kits and have had multiple different heights of lifts. Started with 2” and went to 3.5” and then 6”. My second WJ I started with 4.5” and then jumped to 8”. 8” is the max if you still want to drive it on the road. I’ve noticed that you didn’t flip your drag link to the top of the knuckle. That makes a huge difference is the drivability of WJ’s. Helps with bumps steer and wondering A LOT! You can also flip the tie rod to the top of the knuckles to give you some more clearance of your axle. It’s a popular “upgrade” for just about any Jeep. Sometimes you have to trim some brackets to flip the tie rod. I found that any lift over 2” required to have the transfer case drop installed or you get a lot of driveline vibration. The CV’s or non U joints style couplers of the driveshafts don’t like lifts beyond 3”. Don’t know if this helps 2 years after the fact but I thought I’d throw it out there.
@Wayne Jones where the drag link connects to the passenger side steering knuckle, flip that rod end so the goes down thru the knuckle hole instead of up thru it. You have to drill the hole out and get a taper bushing / adapter (most Jeep or off-road websites sell them). What that does is reduce the angle that the drag link. Helps it from all kinds of drivability issues. You can also flip the drag link over so the link ends go thru the top of the knuckles as well. This just adds clearance. There are a few companies that sell kits to do all this. It’s a high steer kit. They are more popular on the TJ’s and YJ’s.
I’m preaching to the choir, but as you raise the ride height of the vehicle, you not only raise the center of gravity, you change the steering and handling geometry of the entire vehicle. The increased diameter and weight of the tires and wheels adds another variable, which together with the increased load on the wheels bearing and incorrect tire pressure can introduce looseness into the steering. The density or “give” in the various bushings can also add to the feel of looseness, particularly with heavier, bigger tires and the increased ride height. In short, and as you well know, every possible suspension adjustment can have a major effect on ride and steering, and all of it has to be double-checked. Great job so far and good luck in sorting all of this out.
Its amazing to see how far alignment machines have progressed over the years.....just like playing a video game .......it goes green when you get it right!
Even that things a dinosaur. I demoed a new hunter for a week, the heads are spring loaded and just grab right on the tire and no need to level, the machine adjusts instantly. Also you only have to roll back 1 inch and back, steer left to right fast as you want and boom its ready. Its practically cheating.
Congrats on your 200k achievement! Your one hell of a mechanic that has given me a completely different view when doing a diagnosis. Thanks for all of your dedication!
Just discovered your You Tube channel this week and have been binge watching as have been a DYI mechanic for years. I live in WA state where we have almost no snow and little salt to deal with. I am shocked at the amount of rust and corrosion you have on the cars back there. My sister in law lives near Ithaca and was trying to help her buy a good used car via internet and phone this year was an almost impossible feat. Tried to get her to buy new as I know the rust issue is bad back there. Luckily found her a fairly new used car in her price range she actually liked and was pretty rust free. So mission accomplished. I sent her the video you made on that Subaru wagon that was junk. The one thing I would like to know not only the year of these vehicles you work on, but the mileage on them so it would give us who don't live in the rust belt some idea of the amount of rust and corrosion, in a time frame and mileage aspect. I just took possession of my dads 1991 F 150 PU 5.8 auto, with only 88,000 miles and still no rust. Back there it would have been in the junk yard 15 years ago. Love your videos as I believe what you say about people can do a lot of this stuff them selves. But as I get older I am beginning to pay others (with younger bodies) to do some of the harder repairs!
Can you please do an update video on your WJ? How you like it, how you have used it, how it handles on road for daily driving, etc. I bought one and am thinking about lifting it and would like to know how you like yours after lifting it.
It looks like your track bar and center tie rod are not parallel, but it’s hard to tell with that funky bend it has. My F250 had awful bump steer issues when I got it, because the PO had installed lift springs and the track bar and center tie rod were no longer parallel. Returning them to a parallel configuration (several methods available) eliminated the issue.
Always a new learning curve when doing modifications like that. Hope you figured it out and sure you've contacted everyone you can think of to help with a solution. I remember I was cleaning the alloy wheels on my '99 LeSabre and there were a couple gobs of who knows what I cleaned out and they weren't all that big. But ironically on my way to getting a couple new tires I felt this crazy vibration at about 55 and could only think of those 2 gobs. Of course it couldn't be on the ones I was replacing so had all the wheels balanced and was fine. Didn't really think that little amount of what I cleaned off would affect the balance so much. Thanks for sharing.
I fooled around with mine for quite a while and the thing that made the most improvement in handling was the 1 inch rear sway bar. The taller springs made body roll way worse and the sway bar fixed it.
My 1998 Grand Cherokee has factory installed U-joints in the front axle. No CV joints. So far I have only replaced the shock absorbers once. Everything else is still original in the suspension. Engine got a new water pump replaced once, plus new spark plugs, wires, belt and other routine tune-up items. I change transmission oil every 20k miles and engine oil every 5k. It still runs like new. I use Amsoil lubricants only.
Quick way of measuring caster without a machine is to place a magnetic angle finder on the factory indented circles on your front axle tubes near the diff. There's a chart online as to the values to go off of. The indented circles are 90° from the ball joints
I like how your very persistent on getting stuff just right. Most would just send it and say , Well that's what u get with a lift and big wide tires. Thanks for coming in today Fella! Need to bring my 99 2500 with 40s on it to have u align it. Right! Lol
Shove some GoPros under it and what the suspension when it’s acting up. Apples and oranges but I worked on a 65 mustang that did some of the same stuff. Darty on the road, bump steer, and loose feel. Found out the front coil springs were in a coil bind and would give a completely different ride height while driving than parked on the alignment rack. I put a ton of caster in the front and that helped mask it. Also went a little toe out but nothing made as much difference as the new coil springs. Again apples and oranges as vehicles go but the GoPro might reveal what you can’t see.
I really love the suspension/alignment videos. There aren't a lot of good auto videos on alignment especially. I've heard you say before that you don't particularly enjoy doing alignments but like everything else automotive, you do a great job with the adjustments and the explanation. I've had several job interviews in the past where I was asked if I knew how to do alignments and I was a little embarrassed to say no. Just a suggestion on future video topics. keep up the great work and awesome videos!
On the 97 camber adjustment was on the upper ball joints but that was the older cherokee lorado with the earlier body style a little different than yours
it looks like the steering drag link and pitman arm are on a pretty bad angle which would make it steer side to side as the suspension goes up and down. maybe a lower pitman arm would help??
Eric, please keep us updated on what you find. May be doing this conversion but I'm gonna hold off until you figure out yours. Please share what you find out please Sir. God Bless
You need more caster. The big lugs on the tires and the size and weight of them require more caster and toe in. Caster should be 7-8* rather than 4. It’s simply not enough.
You'll figure it out, Eric. One "ah-ha!" moment and you're there. Stick with it; hard part's done! (if you replace the inner axle seal at some point, please film it)
Kevins off road track bar bushings are what you need. I have used JKS, Zone, and Iron Rock and none are as hard as Kevins. They stopped death wobble and made my old Wj ride on rails. MOOG SSD107 is the best steering stabilizer for WJ to band aid some of the steering issues they all seem to have once lifted. Some even go to dual Steering stabilizer.
ive been a professional alignment man for years and im thinking you do need more caster for sure and a drop pitman arm to relieve the bump steer other than that excellent job sir and i very much enjoy your channel
Awesome video Eric! You'll figure out the issues. I have faith in you. I'm slowly upgrading my WK and your new videos have been a ton of fun to watch. Keep up the good work and thanks for being an honest mechanic. Gives much needed faith to the community. I told my wife just the other day, " I wish Eric O lived down here, I'm sure I'm just looking over something stupid".
I got great at doing those Jeep algnments. Never had steering problem. I made sure about the horn ring I think Jeep has a click in it also... Can't recall everyone.
Have you checked into drag link and trac bar angles? Trail forged makes a kit to flatten both angles closer to stock which should reduce bump steer, maybe it can also reduce the overall wandering effect on uneven roads as well. I am going to install it soon (Ultimate Steering Kit)
Toe-in on a solid front axle with T style linkage should be as close to 0° total toe with the axle directly center in the frame . The wheels end up fighting each other if you have ANY toe what-so-ever or if the axle isn't centered. The bigger the tire, the more critical it is. I run 37s on a '02 Ram 2500 with 0° toe and adjustable track bar for a perfectly center axle. Rides straight as an arrow!
I'd pull the front driveshaft and make sure that the AWD is not the issue. I seem to remember similar stories with the NP203 equipped Chevy's. Put selectable hubs in and handling problems went away.
If i had to guess, I'd say it's the new tires. Put the originals back in and take for a ride. I had a car with the exact same wandering/pulling issues and chased it a while, thinking well it couldn't be these brand new tires. I had the frame checked and straightened, a new steering box (old one had a twisted steering shaft), and various front end parts. Nothing fixed it so it was a white knuckler to drive. Finally wore out those tires and put new BF Goodrich TA radials on it like my other car had and low and behold, the car drove great. Could not believe it but there it was, night and day. Near as I could tell, those other tires had a very stiff sidewall whereas the Goodrich did not.
Heck Eric, my brand new Chevy 2500 HD was a mess after I bought it. Hit a bump in the road and I would be in another lane. Steering wheel would turn 5 inches either way before tires would move. After many visits and arguments with dealer, which after a couple of visits, then changed dealerships, it got fixed. Ended up they replaced gear in steering box. What a difference! The first dealer told me that Chevrolet wouldn't let them mess with front end till truck had a 1000 miles on it, I knew that was bull.
The center line ( center of tread width) of your tire and wheel assembly is designed to ride over your bearings.This way the weight of the vehicle is supported by the strength of those bearings. By putting wheel spacers on the jeep the weight of the vehicle is outside of those bearings no support.This can cause wander and weave and premature bearing wear. On rear wheel drive cars with packable bearings the center line of tire and wheel assembly is designed to run over inner bearing. Try taking spacers off and retest drive the jeep.
yes, what you described is (or should be) common knowledge around the off-road community. Any of the mods we do for off-roading capabilities will typically throw the entire vehicle out of it's spec and will lead to premature wear. It's part of the hobby.
I only have a 2 - 2.5 lift on my ZJ, after rebuilding the front driveshaft (axle rzeppa, transfer case double cardan), it had a vibration at high speed. I ended up dialing all caster out of the stock lower control arms which enabled me to get about 75 mph out of the vehicle which is fast enough for me. Have not seen any updates on this vehicle recently, you may not like them but, maybe you could try the offset upper ball-joints. I'll take straight front axles ANY day over IFS, hope to see more of your WJ.
By the way, I replaced my CV axle shafts with el cheapo remans and have zero issues with dry road hunting back and forth. In slippery (snow) conditions with open front diff and limited slip in rear . . . what ever tire gets grip is where it is steering towards. I plan on installing an Eaton Truetrac in the front for the snow. I do not off-road with this vehicle, this is strictly my 86 mile round trip work/daily driver. I also do not have any bumpsteer with all caster dialed out and I hit 75 mph at times on these crappy PA roads. I have some 31 10.5 15 Cooper Discoverer M&S on the way as my current studded tires are on their 3rd season, we'll see how they work.
I would think a steering box upgrade is in order if you haven't already thought about it. I know mine 94 GC was a handful with the OEM box. Wish I had gone to a Red Head or something along those lines.
Eric, that is the down side from aftermarket modifications. On paper everything sound GREAT! until you put them on and a bunch of unknown pop up and more headaches you have. Sometimes one after market modification doesn't agree with another aftermarket modification, with out a mayor hands on mods and lots of time put on. When I do my modification for my rig need to be able to be daily driven if need it and be able to take highways anytime, because even if you are building a off road rig, in order to get to the site you will be wheeling you will have to drive on the road and highway unless you town or haul you rig until the off road site. Imagine if you want to go to the Moab and have a nice week of vacation with the family and enjoy the several trails that it offer, you will need to drive on highway to get there. So what ever you do, make sure it is pleasurable to drive and reliable. If that mean remove some mods and going with other options, let it be.
Moog makes adjustable upper and lower ball joints that will put you back properly aligned and steering, and wandering. You will need to drop the transfer case at least one inch, probably more. Lifted Jeeps have a tendency towards a type of 'bump steer' that involves the driveshaft dragging or hanging up in the transfer case. I bring that up when you get the new ones. In Jeeps the 'drag link' is usually called the 'track bar', and less commonly a 'panhard bar, I think it depends on where the guy you're talking to is from or got his training. Jeep toe is 1/16"-1/8". Your 0.1" (1/10")is within that range. Make sure that all your greasable fittings are greased, some manufacturers ship them dry. CV shafts are certainly smoother than U-Joints, they are older and tougher technology. Please remember that penetrating fluid is your friend. -just sayin'...
after few years of alignment practise I had you will find imho the caster is what you should look at first more caster should make it harder to steer from a strait line as the wheels will want to 2caster" to the ahead position i.e. think shopping cart
Hi Eric, I've seen this problem before and when you raised the body you have to count with the pitch angle difference between the steering box and knuckle, and also the angle of attachment from the tracking arm bracket to the axle. I hope it helps. Keep with the videos, great stuff.
Hey Eric, great WJ videos, I think cv conversion with the spacers are your issues. With those tires & dialing in ALL that geometry on a WJ mite be what's going on. Your a good man/ great mechanic.You keep me going on my lifted 2000 Grand. Thanks.
Thanks for the tutorial on the WJ. I just bought one myself and am in the process of chasing some bugs . Seeing the software reactions to your adjustments was helpful. I know have a better under standing. Also, I found one with the " Select Trac" system and like the 2WD vs AWD mode.
The problem is likely in the wheel spacers. When you push the wheel out like that it messes with the steering geometry and can really cause some issues.
Had this problem, replaced the rear lower control arms and the Y joint with upgraded bushings and joint. Im telling you its not alignment its those arms and joint. Im riding on a 4inch RC lift on my 04 WJ AWD all time. No shaft vibration and i dont get the fish tailing feeling. No death wobble etc. Only thing i have is a little play in the steering, im guessing a new or tightened steering box would solve that.
Eric, Great video - alignment machine looks really cool! I love when you are at your Dads/brothers shop - its a cool place. I know you will figure out whats going on and fix it. SMA#1 God bless Paul
Wow! That stinks to have little hiccups, but like you found the issue before, you'll figure it out again. Sometimes it just takes walking away. .. then getting that "aha!" moment...
Was thinking about straight ahead on the toe. And I see where some folks have a brace between the steering gear box and off side unirail. Not that I know anything.
Rule of thumb down south....if you want it to be nice on the highway, then no more than 4" of lift. If you want to conquer the mud holes, and run 44" tires....then raise it to the sky with a body lift and six inch chassis lift. Put in on a trailer on the highway.
gustavo munoz a drop pitman arm would make it worse. The first and foremost thing to stop bump steer on a quadra link front suspension is to have the track bar and drag link be parallel. If he drops the pitman arm and leaves the track bar they won’t be parallel anymore.
Amazing how complex steering issues can be when a vehicle is lifted. Fortunately most lifted trucks are dedicated to off road use. I wonder how hard it would be to tweak the camber, it looked out of adjustment on your machine but eyeballing the tires it looked OK.
If I'm not mistaken, I believe you can get adjustable upper ball joints for these to correct camber. Entirely possible that Iron Rock or some other off-road company has another type of solution as well.
I do a lot of alignments. Are you sure you didn't fudge those numbers? every once in a while you see a solid axle vehicle and want to tell the customer they got real lucky and it's one to hold onto. Even toe in the rear, just a slight toe in. Doesn't get much closer to even camber side to side with good numbers. Definitely one of the rarest.
I’m getting an alignment next week and hopefully it gets rid of my Jeep driving like shit. Little bit of death wobble and constantly chasing it back and forth going down the road. My setup is - 2 1/2” budget boost, JKS adjustable trac bar, Moog trail boss steering stabilizer, fat bobs extended sway bar links and it’s sitting on JK wheels with 255/75/17’s.
Well the one thing you didn't install was a dropped pitman arm. I can't believe they didn't include one in that kit. That will have a direct impact on steering feel. When the drag link is up real high it has a less direct force on the knuckle/tie rods.
How do you keep dirt out of the axle shafts. You threw out the ripped CV boots. Are there boots to install over the U joints? Yes I know there is a seal deep inside the tube. Getting dirt out of the tubes may be a PIA.
What about RCV axles? They are supposed to be supper strong and have a high range of steering angle. They probably make them for your front axle but they are pricey.
I know this video is about 2 years old but I’m new to the channel. I’ve had 2 WJ’s. They are great but have their quarks.

Also the rim to tire width. the rims need to be wider to give the sidewall more stability.
@@inthenose5411 Thank you , when he said he was using the factory wheels with that size tire I knew he would have an issue with stability
People often overlook this, especially putting wheel spacers on. Then they wonder why bearings go bad quick. Great comment.
Its amazing to see how far alignment machines have progressed over the years.....just like playing a video game .......it goes green when you get it right!
Even that things a dinosaur. I demoed a new hunter for a week, the heads are spring loaded and just grab right on the tire and no need to level, the machine adjusts instantly. Also you only have to roll back 1 inch and back, steer left to right fast as you want and boom its ready. Its practically cheating.
thats not a top of the line machine too, john bean's are in my experience the least preferred machines for alignment. hunter is where its at
@j bowers is your steering wheel a turned a quarter to either side and do you have excessive tire wear?
Happy you found and cured the problem with the defective ball joints! That WJ is way too nice to get rid of!
Trying taking off the wheel spacers that should take care of the wondering worked really well for my jeep
He can't, it's part of the ujoint conversion.
@@TheNemosdaddy They're talking about the wheel spacers, not the bearing/hub spacer
Even here in the south I used antiseize on tie rod ends a few times I sealed that split on adjusting sleeve to waterproof it.

Jeep offeres a one degree offset upper ball joint which helps with caster split and camber adjustment.

In the green always feels good - especially for the tire budget!

I bet it needs that drop pitman arm to make everything a little more parallel.
yep, it's off far enough to make it change big time with any suspension flex

I know with the rough country lift the supply a transmission drop mount just for that but that was for a 8 to10 inch lifton 33s
Aint nothin better than a good ol SMA double header on a Tuesday night!
You are right when you said tire pressure, lower your tire pressure to get a better Tire patch on the road!
Yep. He'll get a better center-feel as well.
Quick way of measuring caster without a machine is to place a magnetic angle finder on the factory indented circles on your front axle tubes near the diff. There's a chart online as to the values to go off of. The indented circles are 90° from the ball joints

That would make sense. The angle of the drag link would have to be excessive with that much lift.
@@markchidester6239 Yes that was my thought.
Eric, please keep us updated on what you find. May be doing this conversion but I'm gonna hold off until you figure out yours. Please share what you find out please Sir. God Bless
It's a Bad/Tight Ball Joint.
You need more caster. The big lugs on the tires and the size and weight of them require more caster and toe in. Caster should be 7-8* rather than 4. It’s simply not enough.

Ouch!!! I remember a few videos back you mentioned that this happened, I'm sure you will figure it out if you didn't already by now. You got this!
Offset upper and lower balljoints for drive line vibes. I found 1.75° and 2.5°(iirc) upper and lower respectively. As well as a D30R (high pinion).
......and check out Checkered Flag Tire to balance your mudders. Work quite well for my 32" BFG KM2s(shocked the shit out of me)
Beautiful Rig...I also have a lifted WJ. They are very nice if done correctly.
Toe-in on a solid front axle with T style linkage should be as close to 0° total toe with the axle directly center in the frame . The wheels end up fighting each other if you have ANY toe what-so-ever or if the axle isn't centered. The bigger the tire, the more critical it is. I run 37s on a '02 Ram 2500 with 0° toe and adjustable track bar for a perfectly center axle. Rides straight as an arrow!
I'd pull the front driveshaft and make sure that the AWD is not the issue. I seem to remember similar stories with the NP203 equipped Chevy's. Put selectable hubs in and handling problems went away.
Enjoyed the alignment, that's some high tech kit.
That’s old technology already buddy but a new rack is like 40,000.
I love "The Self Made Auto Channel" Best thing for a NY WJ is off road...No Salt=No Rust
If i had to guess, I'd say it's the new tires. Put the originals back in and take for a ride. I had a car with the exact same wandering/pulling issues and chased it a while, thinking well it couldn't be these brand new tires. I had the frame checked and straightened, a new steering box (old one had a twisted steering shaft), and various front end parts. Nothing fixed it so it was a white knuckler to drive. Finally wore out those tires and put new BF Goodrich TA radials on it like my other car had and low and behold, the car drove great. Could not believe it but there it was, night and day. Near as I could tell, those other tires had a very stiff sidewall whereas the Goodrich did not.
try it without the wheel spacers . easiest thing first
If you up grade to adjustable shocks I think you will see a difference and can change the harsh ride
Heck Eric, my brand new Chevy 2500 HD was a mess after I bought it. Hit a bump in the road and I would be in another lane. Steering wheel would turn 5 inches either way before tires would move. After many visits and arguments with dealer, which after a couple of visits, then changed dealerships, it got fixed. Ended up they replaced gear in steering box. What a difference! The first dealer told me that Chevrolet wouldn't let them mess with front end till truck had a 1000 miles on it, I knew that was bull.
If your gonna play on the rocks in Moab Utah, you gotta be able to get there.
The center line ( center of tread width) of your tire and wheel assembly is designed to ride over your bearings.This way the weight of the vehicle is supported by the strength of those bearings. By putting wheel spacers on the jeep the weight of the vehicle is outside of those bearings no support.This can cause wander and weave and premature bearing wear. On rear wheel drive cars with packable bearings the center line of tire and wheel assembly is designed to run over inner bearing. Try taking spacers off and retest drive the jeep.
If the spacers come off, he'd have to go to a different offset wheel for clearance. It would relieve some bearing stress though.
BS!
@@franknewling1139 I think that would have the same effect on the bearings.
yes, what you described is (or should be) common knowledge around the off-road community. Any of the mods we do for off-roading capabilities will typically throw the entire vehicle out of it's spec and will lead to premature wear. It's part of the hobby.
Scrub radius.
I only have a 2 - 2.5 lift on my ZJ, after rebuilding the front driveshaft (axle rzeppa, transfer case double cardan), it had a vibration at high speed. I ended up dialing all caster out of the stock lower control arms which enabled me to get about 75 mph out of the vehicle which is fast enough for me. Have not seen any updates on this vehicle recently, you may not like them but, maybe you could try the offset upper ball-joints. I'll take straight front axles ANY day over IFS, hope to see more of your WJ.
By the way, I replaced my CV axle shafts with el cheapo remans and have zero issues with dry road hunting back and forth. In slippery (snow) conditions with open front diff and limited slip in rear . . . what ever tire gets grip is where it is steering towards. I plan on installing an Eaton Truetrac in the front for the snow. I do not off-road with this vehicle, this is strictly my 86 mile round trip work/daily driver. I also do not have any bumpsteer with all caster dialed out and I hit 75 mph at times on these crappy PA roads. I have some 31 10.5 15 Cooper Discoverer M&S on the way as my current studded tires are on their 3rd season, we'll see how they work.
I would think a steering box upgrade is in order if you haven't already thought about it. I know mine 94 GC was a handful with the OEM box. Wish I had gone to a Red Head or something along those lines.
Great Video. I know you will figure it out because you figure out problems that other shops can’t.
Eric, that is the down side from aftermarket modifications. On paper everything sound GREAT! until you put them on and a bunch of unknown pop up and more headaches you have. Sometimes one after market modification doesn't agree with another aftermarket modification, with out a mayor hands on mods and lots of time put on. When I do my modification for my rig need to be able to be daily driven if need it and be able to take highways anytime, because even if you are building a off road rig, in order to get to the site you will be wheeling you will have to drive on the road and highway unless you town or haul you rig until the off road site. Imagine if you want to go to the Moab and have a nice week of vacation with the family and enjoy the several trails that it offer, you will need to drive on highway to get there. So what ever you do, make sure it is pleasurable to drive and reliable. If that mean remove some mods and going with other options, let it be.
Moog makes adjustable upper and lower ball joints that will put you back properly aligned and steering, and wandering. You will need to drop the transfer case at least one inch, probably more. Lifted Jeeps have a tendency towards a type of 'bump steer' that involves the driveshaft dragging or hanging up in the transfer case. I bring that up when you get the new ones. In Jeeps the 'drag link' is usually called the 'track bar', and less commonly a 'panhard bar, I think it depends on where the guy you're talking to is from or got his training. Jeep toe is 1/16"-1/8". Your 0.1" (1/10")is within that range. Make sure that all your greasable fittings are greased, some manufacturers ship them dry. CV shafts are certainly smoother than U-Joints, they are older and tougher technology. Please remember that penetrating fluid is your friend. -just sayin'...
after few years of alignment practise I had you will find imho the caster is what you should look at first more caster should make it harder to steer from a strait line as the wheels will want to 2caster" to the ahead position i.e. think shopping cart
Eric, Put a snow plow on the front of this thing. Your in the right area for it.Besides, plowing snow is fun and profitable.
Hi Eric, I've seen this problem before and when you raised the body you have to count with the pitch angle difference between the steering box and knuckle, and also the angle of attachment from the tracking arm bracket to the axle. I hope it helps.
Keep with the videos, great stuff.
Hey Eric, great WJ videos, I think cv conversion with the spacers are your issues. With those tires & dialing in ALL that geometry on a WJ mite be what's going on. Your a good man/ great mechanic.You keep me going on my lifted 2000 Grand. Thanks.
I say crank the caster up to where it's supposed to be and get a clocking adapter for the transfer case to bring the front output down an inch or two.
Thanks for the tutorial on the WJ. I just bought one myself and am in the process of chasing some bugs . Seeing the software reactions to your adjustments was helpful. I know have a better under standing. Also, I found one with the " Select Trac" system and like the 2WD vs AWD mode.
The problem is likely in the wheel spacers. When you push the wheel out like that it messes with the steering geometry and can really cause some issues.
My truck did the same thing. After all the headaches I lowered the tire pressure and my problem went away. Hopefully your dilemma is that simple. Jim
Had this problem, replaced the rear lower control arms and the Y joint with upgraded bushings and joint. Im telling you its not alignment its those arms and joint. Im riding on a 4inch RC lift on my 04 WJ AWD all time. No shaft vibration and i dont get the fish tailing feeling. No death wobble etc. Only thing i have is a little play in the steering, im guessing a new or tightened steering box would solve that.
I enjoy all your videos, helps me understand a-lot of repairs that I do. Would like to see some Ford 6.2 repairs.
Any updates on the wj?
Eric,
Great video - alignment machine looks really cool! I love when you are at your Dads/brothers shop - its a cool place. I know you will figure out whats going on and fix it.
SMA#1
God bless
Paul
That's kind of a bummer that the modifications has taken you to this point. I bet by now you have figured it out and your just making us wait. :)
Maybe.... ;)
Jeep looks ready to ROCK & Roll Sweet 👍👍
It's that goddamn bolt-on performance!
Wow! That stinks to have little hiccups, but like you found the issue before, you'll figure it out again. Sometimes it just takes walking away. .. then getting that "aha!" moment...
Or sometimes it takes one more beer! LOL
Figuring out the issues makes this fun and potentially very costly.
You'll figure it out! Awesome job!
Hey Eric, how about installing a drop-down pit man arm on your steering box if you already haven't?
Them Snapon pliers you were using to adjust the tie rod are so handy eh. I use them all the time on wheel alignments.
Dennis Reelie I have two pairs. One big and one small. They r pipe wrenches.
Was thinking about straight ahead on the toe. And I see where some folks have a brace between the steering gear box and off side unirail. Not that I know anything.
Rule of thumb down south....if you want it to be nice on the highway, then no more than 4" of lift.
If you want to conquer the mud holes, and run 44" tires....then raise it to the sky with a body lift and six inch chassis lift. Put in on a trailer on the highway.
Are you ever going to do an update on this? Did you do a diff drop lift on it yet? What kind of lockers?
And a drop pitman arm should help with bump steer and correct some steering angles
gustavo munoz a drop pitman arm would make it worse. The first and foremost thing to stop bump steer on a quadra link front suspension is to have the track bar and drag link be parallel. If he drops the pitman arm and leaves the track bar they won’t be parallel anymore.
@@Justin1701xbox it needs a trac bar drop bracket as well should take care of it
@@Justin1701xboxlook again. They weren't parallel after all the mods were done so there's part of the problem.
Amazing how complex steering issues can be when a vehicle is lifted. Fortunately most lifted trucks are dedicated to off road use. I wonder how hard it would be to tweak the camber, it looked out of adjustment on your machine but eyeballing the tires it looked OK.
If I'm not mistaken, I believe you can get adjustable upper ball joints for these to correct camber. Entirely possible that Iron Rock or some other off-road company has another type of solution as well.
On a 4wheel drive optimal settings are 0 camber and 0 toe
I do a lot of alignments. Are you sure you didn't fudge those numbers? every once in a while you see a solid axle vehicle and want to tell the customer they got real lucky and it's one to hold onto. Even toe in the rear, just a slight toe in. Doesn't get much closer to even camber side to side with good numbers. Definitely one of the rarest.
A drop pitman arm should help to give you back some steering response so it won't wonder as bad
You'll figure it out, looking forward to seeing you solve the mystery.
i hope for a video with this monster jeep in the upcomimg winter and the big snow
It looks so cool. Looks great!
Do you have any updates on this? I am curious as to what you've done to correct the handling issues
I’m getting an alignment next week and hopefully it gets rid of my Jeep driving like shit. Little bit of death wobble and constantly chasing it back and forth going down the road. My setup is - 2 1/2” budget boost, JKS adjustable trac bar, Moog trail boss steering stabilizer, fat bobs extended sway bar links and it’s sitting on JK wheels with 255/75/17’s.
Well the one thing you didn't install was a dropped pitman arm. I can't believe they didn't include one in that kit. That will have a direct impact on steering feel. When the drag link is up real high it has a less direct force on the knuckle/tie rods.
Eric bushwhackers would look killer on there and you have to trim would help a lot with your clearances
with those much bigger diameter tires, are you going to correct for speedometer error. I am sure the speedo runs a lot slower than it should.
Nice Jeep unlimited parts in the Bone Yard. Just grab a second set of Axles. Did you get it to ride better going down the rd?
How do you keep dirt out of the axle shafts. You threw out the ripped CV boots. Are there boots to install over the U joints? Yes I know there is a seal deep inside the tube. Getting dirt out of the tubes may be a PIA.
What about RCV axles? They are supposed to be supper strong and have a high range of steering angle. They probably make them for your front axle but they are pricey.
I have no doubt that you will get it figured out.
