A couple things to add for anyone doing this swap, if you want to do the Camo method or Toyota unit bearing mod, birfs will need to have the snap ring removed from the outside of the inner shaft. This will allow you to pull the knuckle and not mess with wheel bearing settings. Also, if you do this you will need to do the Martack mod to the inner splines of the shafts to keep them from floating too far into the side gears on the diff.
We do a similar swap here in Iceland all the time but we space the brake disc back to its original position using a spacer and longer bolts to bolt the disc to the hub, hope that makes sense but the outcome is similar, I imagine with our way we never have issues with the rims touching the caliper and the splash shield serves its original purpose
I did a very similar swap many years ago. Except I used FJ rotors, ifs calipers and hubs. Not sure what the difference between the rotors is. I didn't need a washer for mounting the calipers though. Now would be a good time to upgrade the rear with the factory solid axle disk brakes you removed.
That's where I'm at. But the ifs rotor is about 11/16 thick. The FJ40 is 1 1/8" thick. Calipers are not gonna slide over it. 🤔just how did you get this to work?
Dude, it was awesome seeing the truck in person. I only wish those hubs would have fit better... ive had the ifs hub mod done on 3 of my vehicles now, with 3 different sets of rims, and never had any major clearancing issues... had no idea that rims could mess it up so badly haha. At least you got it sorted out creatively... I also wish i had the mazda finished when i came down haha. Oh well, next time, and then we'll go wheelin.
@@brycesnevadatrapline3712 I've got the same axle under my mazda on my channel. I'm running 37x12.50-15's so 15's do fit. It's all about the backside of the rim and if it clears the caliper.
Same issue but with some Pro Comp 62’s I think, the alloy ones. Turns out they are a -19 offset. I’m guessing each negative number is a 1/4” in or out. A set of wheels with -18 or -16 (closer to 0 offset) will eliminate the use of spacer all together. I think stock wheels run a -6 to -9 on offset, down fall of stock wheels there all 7” wide. And if you need studs you can pull the studs from your spacers. If your running alloy wheels like I am the rear studs aren’t long enough. The spacer studs are plenty long enough and in my case I have an extra set of 12 studs cause I had spacers on the front and the rear.
I’ve done the same swap several years ago with the help of my dad who is a machinist. Fortunately my wheels fit with only minimal clearancing of the calipers.
What year ifs hubs did you end up going with? I have a 1991 toyota 4runner with ifs obviously and I acquired a 85 Solid axle housing. So I have to build the axle from the ground up and was wondering if I could get away with using my ifs hubs. Thanks.
Hello I picked up a set of 1984 Toyota axles. So I bought this Front U-Bolt Flip Kit 1979-1983, Rear 1980-1995 kit from trailgear but the Ubolts are wider than the axle, if that makes sense. I’m trying to use this for the rear axle. Do I have an axle from another year?
I'm looking at $2k-$2.5k worth of work I need to do to my IFS in my '94. I have a 3" lift and 31s with the stock gearing. I am wanting to go to 37s in a couple years, ultimately. I am wondering if it would be worth it to go ahead with the SAS, and if it would possibly be around the same price.
@black_metal_luvr Id SAS if you want any bigger than 35s. Plus at 2.5k your better off anyways, you can definetly do it about the same price if you do it all yourself.
@DirtGarage I'll see what I can source. I see LCE has a kit for $2100, if I could just get a good deal on a front axle with 4.10 gears. I'll give LCE a call tomorrow and see what they can recommend. I definitely want to do all of the work myself. Can I use my existing OFS hub, or do I have to purchase a specific one? Really appreciate you getting back to me, btw.
@black_metal_luvr Trail Gear is best bang for buck when it comes to SAS kits. If you have a non abs truck your current hubs will work once machined. But SAS kit usually comes with spacers so its not necessary
@@DirtGarage Okay. Yeah, it's non-ABS. I don't believe Trail Gear had anything for lower than 5", and I currently have 1.5" body and 1.5" suspension. I guess I can call them and see for sure.
I'm going through this process right now. I get the impression that you're sliding the whole IFS hub on, does that mean you're skipping out on the snap ring for the birf? Is the outer snap ring necessary?
My '83 toyota pickup 4x4 is stock solid front axle (not SAS) w/37"X14" tires, & 17" steelies. Are my axles narrow? If so, would IFS Hub mod work w/ steelies? Thnx.
IFS hub swap... do you go with the hubs off of a 3rd gen pickup/4Runner? Or could you go with 1st gen Tacoma hubs? This applies to both 1st and 2nd gen solid axles im assuming...
Do you happen to know what can solve death wobble with the SAS on a toyota pickup? I have read a lot and most people say its the caster angle. Just wondering if you have any input?
Could be bad caster , worn trunnion bearings , bad alignment ,worn steering components , worn spring bushings , just have to go through your front end one component after another
Hey ya just wondering if this can be done with an 80 series swap into my surf / 4runner. Ive already done the swap and have all the hubs etc they thing is the 80 series is already 2 inches wider than the rear ifs diff, so I've got my wheel offsets to make it the same width front and rear so if I were to do this mod, the front axle would be 4 inches wider than the rear so I would just get 2 inch spacers for the rear. But than my wheels don't fit over my 80 calipars, they only just nick the rim so may need 15mm spacers or something so hopefully its algood 15mm wider in front. But yeah please let me know of they will fit the 80 series axle thank you
If I wanted to use the ifs hubs and rotors from my 89 4Runner on a sas like yours, would I be able to? Do you know if the modifications would be the same?
Hey man Im in the process of getting all of the parts together for my 85. What year Tacoma rotors did you use 95-04 im assuming? any help would be awesome!
@@jibaritomx ok thanks. Hey another quick question are the wheel bearings the same size on ifs hubs as solid axle hubs? I just got my ifs hubs and already had a full set of sa bearings sitting in the garage. Wondering if they will work
@@palaciosivan100 Even auto locking hubs work. As long as the hubs are from early IFS with torsion bar suspension, it will work on the Toyota solid axle.
Can you do this swap and use the rotors off the 86-88 pickups instead of Tacoma rotors? I have 2 sets of rotors for the 86-88 from my current build but will be picking up a solid axle soon.

This is an emotional moment for me.. finally... someone else in the world that understands, ‘grinded it’...
Haha I think your the first to ever call me out on that. But totally something I say alot.
Your 2UZ project got me watching, but hearing that, sealed the deal. Appreciate y’all.. subscribed..
TY for all the info, I’ve learned so much about Toyota’s from your videos, coming from the Jeep world , you’ve been super helpful and informative
Awesome! Thank you!
My 85 4runner is original, only added 15x10's on 35's tires are about 1in past the fenders. perfect stance.
Yup! No need to widen a factory solid axle 85. Your axles widths should already match.
Awesome choice my friend I run the same setup on my truck and also shaved my calipers for it to fit.
Right on!

Loved the video and I’ll be doing this to my 85 4runner for sure. Thanks for making the video, definitely have a new sub!
Thanks for watching! Worth while mod, I would put a whole IFS rear housing in the 85, wider stance, better brakes, etc.
Nicely done! Making a spacer from the old calipers blew my mind
I wanted to go wheeling the next day. The spacers where 2 weeks away! So I made the spacers and canceled my order 😂

Did this swap on my yota. Love it. I just got a 5mm spacer and cleared my v6 calipers
It makes it around 3 inches wider, right?
@@SubePelayo928 yep
Awesome!
Do you know if you can still fit 15" rims after the rotor and caliper upgrade?
Same thing I’m wondering
@@loucksrylee_6060 I did it and you can, it’s especially easy if your wheels have a big offset.
@@brycesnevadatrapline3712 so Tacoma calipers work. Wonder if they’d work with my 8” wide wheels
@@loucksrylee_6060 yeah i used 96 4runner calipers. i can’t be totally sure about the rim width though. mine have a fair amount of offset

Your 91 hubs are the same hubs I used in this video! Will work great. Need 86-94 IFS Hubs.

Hi, I have a question for you are you selling wire harness? If you do tell me
what year taco rotors
Just making sure I understand. Stock 85 manual hubs will bolt directly on ifs hubs?
Yes. 85 Locking hubs will bolt to IFS hubs.
Any idea what model of Toyota I will need to look for in the UK for hubs and disks ?
I want to upgrade my brakes in the front to the bigger rotors and V6 calipers, could you use them and do the tacoma rotors and the IFS hub upgrade?
I'm looking at $2k-$2.5k worth of work I need to do to my IFS in my '94. I have a 3" lift and 31s with the stock gearing. I am wanting to go to 37s in a couple years, ultimately. I am wondering if it would be worth it to go ahead with the SAS, and if it would possibly be around the same price.

What brand and size are your leaf spring packs on the front of your truck?
Love it. Question. What about the cv axle stub? Do you need to modify it?
Nope! Stays the same length. This just moves the wheel mounting surface out.

when i do this do i need new calipers?
Do you know if these ifs hubs will work on a fj80? Are the stubs/spindles the same diameter?

what year tacoma rotors did u use
I did this on my 02 2wd Tacoma to run 15in bullet holes
What size spacer/washer did you use to space out your calipers?
I'm not actually sure about this, I went to auto parts store and bought the thickest 1/2 washers available, ended up working perfectly!
Do you happen to know what can solve death wobble with the SAS on a toyota pickup? I have read a lot and most people say its the caster angle. Just wondering if you have any input?
In my experience death wobble has always been caused by worn out leaf / frame tube bushings, or tie rods.
Could be bad caster , worn trunnion bearings , bad alignment ,worn steering components , worn spring bushings , just have to go through your front end one component after another

Next time u can use 03 - 06 toyota matrix wheel stud they fit perfect and u have plenty thread if u are using aluminum wheels!
I already actually swapped mine for Matrix studs. Found that tip on a forum after making this video.
Yes i did it on mine 77 it worked great on my truck great vids i am also building my truck and making adjustments
Axle stands be a Good idea !
If I wanted to use the ifs hubs and rotors from my 89 4Runner on a sas like yours, would I be able to? Do you know if the modifications would be the same?
It would be exactly the same! You need the IFS hubs, and Tacoma rotors, then your set!
Do you need ifs calipers or Tacoma calipers or the sold axle calipers
IFS calipers
Hey man Im in the process of getting all of the parts together for my 85. What year Tacoma rotors did you use 95-04 im assuming? any help would be awesome!
I used 98 specifically. Not sure if they changed in later years.

Is there a particular year ifs truck/4-runner. Or will any year work?
Any year will work i got 91 4runner on mine with no problem thery were auto locking just swap your manuals
What rotors did you use? Ifs?
sir, do you need to replace birfield shafts for this setup??
Nope. Still stock birfs!

dirt garage do you know if ifs hubs from a 1998 taco will work for this swap? Or are they different then 86-95 ifs hubs?
Need earlier IFS Hubs, 86-95
You can use Tacoma brakes also or tundra brakes, front range offroad tacoma brake mounting kit...

Hey man in middle of doing this now what year of Tacoma rotors ? Want to order tomorow 😁🤘
1998
Are they the same rotors as the 3rd gen 4Runners ?
What year tacoma rotors fit ifs hubs without having to mill the hub
None as far as I'm aware.
@@DirtGarage ok what year Tacoma rotors are you using ?
whats the resulting new width for wheel mounting surfaces?
Adds 3", so in theory total width is 58.5"
What year caliper did you use?
My stock ones. So 89
