You're very brave.. I know this is a lot of work, but I think the hardest part of this kind of job is not breaking/damaging something. Awesome work man!
So far so good lol... I don’t wheel a lot or do crazy things lol
@@PhoRunner Ok good, but I wasn’t referring to off-roading. I meant not breaking something when taking it apart/disassembling it.
Lol oh yeah... it wasn’t too bad. I wasn’t really setting gears so I was comfortable with it
Just had to swap both my front and rear after blowing them so I know the pain. Glad I didnt have to rebuild my carrier and had a spare to swap in. Props on getting the diff in solo.
lol
great video brother! I'm getting ready to do this very thing on my 01 Taco with ADD. thanks for such a realistic, informative and super helpful video! thanks for taking the time to put this online
No problem!
You should do a review video on how you like the locker
Pure awesome. High quality video and super informative! Thanks a million brother!
Thanks! The lockers been great!
Dude, I laughed so hard when you put the lunchbox in the freezer full of food with no wrapping whatsoever.
Don’t tell my wife lol
Love it! True Asian. Working on Toyota while wearing sandals. Also if you're struggling with the vacuum lines on the ADD. You can always unbolt the unit from the front diff and push it out the way until you get the front diff off.
Lol. Good tip.
Finally did this and I couldn’t be happier. I didn’t have to touch the trans either.
Wow nice lol . Mines been solid so far!!
Is the feasible for a daily driver
Mines a daily driver so yes. But only for the front. I would not do this in the rear.
@@PhoRunner thank you...I cannot afford an actuator air/electric locker for the front... I might get my hands on an oem E-locker for the rear.... Going to check your channel for a write up
Please know that your videos and info have helped me build a very capable truck.... Video by video....
Awesome. I don’t have an install on the elocker but maybe I’ll document it one day. It was before my UA-cam days hehe
Definitely recommend doing the e locker mod it’s nice being able to use it in 2wd and 4h
Yeah I already have that done on mine
Both a friend and I are wanting to install this for IFS on a 98 runner and 95.5 Tacoma, great video. Some basic questions #1 it doesn’t lock when in 2wd right? #2 how is the reset when making small turns off-road? Would love to see a video of it performing!
If you are installing in the front, you don't need to worry to much about this making noise since the front will have ADD (only locks when in 4wd) or manual hubs. In the rear, on corners, make sure you don't give it too much throttle or it'll bang real hard.
Video coming soon for locker action. I'm taking it to the snow very soon!
2nd line: "Today I got a pretty exciting project...." and then hours of work, cursing, sweat, and (I'm sure) many tears later -- it looked more torturous than "exciting". Btw, I'm loving the flip flops--you're just missing the socks -- ah you know what I mean...haha
Anyway, can you provide some feedback how you like this thing? Maybe make a follow-up video? I'm thinking of getting them for the rear, but worried about winter driving... Thanks!
It’s been great. I’ve gone out in the snow and some sand and not too bad. Some tight turns bind it up but just a bit of muscle to overcome. I was worried about drivability but not too bad. Just no throttle on tight turns.
Nice, I'm 559YOTAS too. Hows the spartan lockers do you have any video?
dumb question, but if I were to go with the spartan locker up front do I need onboard air? Thinking about getting this one or the eaton elocker
I have a 4th gen. I ripped my front diff out and took it apart, and figured out this locker doesn’t fit in mine 😪 they changed the front diff to a clamshell and it’s totally different…
This is a clamshell too. You might need a different part since the size is different in the 4th gen.
@@PhoRunner yeah I don’t think Spartan makes lockers that fit my front diff
I am getting ready to do the front manual hub lock conversion, lifting the suspension about three inches with old man emu coil springs and Bilstein shock absorbers on my 1996 Toyota 4Runner. I am also contemplating the installation of a "lunch box" type locker in the front differential, but I am being advised otherwise by "some people" because they said that a front locker would ruin my cv axles, when the 4X4 is activated, specially when turning.
My question to you is, have you had any problem with the cv axles since you installed the locker? And if so, was the problem aliviated with the installation of the differential drop kit?
I would appreciate your input and thanks for your time and your videos, they are very informative>
The spartan locker will cause binding but it has that ratcheting mechanism in there to allow it to unlock on turns. Just don't be accelerating too hard when you got that steering wheel turned as it'll cause a loud clunk. So far, I haven't experienced any of that daily driving. When it's up front, you have ADD keeping it disengaged so should be fine driving on road.
Off roading, you just take it slow and you won't lose CV axles. It's the hopping that kills CVs. You'll have to get use to the clicking on turns in 4x4 but i've used my 4x4 in snow, rock, dirt and it's all been fabulous. I was regretting it at first but after I started using it, i realized it's not a huge issue at all. I used to drive on 2wd intentionally to avoid the loud bangs but it actually doesn't happen that often or at all to be honest.
@@PhoRunner Thanks for the information! Keep up the good work!!
Thinking about doing this to mine when i swap in the rear elocker and manual hubs. Your videos give me great advice and tutorials. Off subject but what front bumper is that?
ARB tacoma bumper
@@PhoRunner Do you have a video of installing it? Does your 4runner have a body lift?
@@danielmiller1856 i do not but TImmy the toolman does.ua-cam.com/video/Wey2f8n0Klc/v-deo.html
Hey really enjoy your channel. How is the front locker working out for you? Any new concerns or issue with it? I think i am ready to purchase and install a Spartan front locker. Thanks from the central coast
!
No concerns or issues. Originally I was worried about driving in snow with them but all that disappeared when I tested them. Just light throttle and let the ratcheting happen and it drives just fine.
Great video! Are you still running Spartan locker in front? So you cant even tell its there unless you put it in 4wd? Thank you for this great channel!!!
Spartan up front and yes I can’t tell at all unless it’s in 4wd. Even if I lock my hubs and drive in 2wd, it’s like it’s not there which is great for dailying
Thank you so much for your channel it is my go to!!!
Great video tutorials bro, disregard the comment on your manual hub video front diff seals.
yup had a nice time changing those lol
Next time to remove the front diff very easily just remove the output flange (that attaches to the driveshaft) from the differential and the diff will clear the bell housing no problem.
Hmmm I was thinking about doing this since I’ll be regearing my front diff soon. :)
PhoRunner Channel Regearing your front diff? Does that mean you’re going full regear soon too?
Yup!! And this trick worked amazing for removing it!!!
PhoRunner Channel Excited for this video! Your runner will be an absolute weapon
Lol I didn’t film The regear and glad I didn’t because it was a disaster lmao. Maybe I’ll do a rundown video haha
Has anyone tried removing the rear mount from the diff before trying to pull it out? I'm not sure if both mount bolts (one on the top and one on the bottom) can be accessed with the diff in place. If that works, you might not need to move the diff upward for the mount stud to clear the frame member. Just a thought. I'm getting ready to do this over the weekend.
No access
Do you have to have the manual hub conversion on the kzn185s before u put these style of lockers in?
You can put the locker in without doing manual hubs
Hi .. first of all great build ! .. I have a question for you, do they still make clicking noises when on 2wd ? Tia
Nope. No noises since it’s ADD. I wasted my money.
@@PhoRunner why you wasted your money? Its not good ?
I was misinformed lol. Oh wells.
So if you have ADD you can't have a front locker?
That job looks like a real pain in the ass...but well done! Have you had an opportunity to take her out to test yet?
i have not! i've been too busy!
Question; I'm pretty sure I have a locker in the front of my 93 4 Runner. When I had it jacked up I locked in the hubs and both tires turned the same direction. Plus I think it has 5.29 Yukon gears because it has lots of power for a 3.0. My question is when it snows in my open diff Geo Tracker 4x4 I can just lock the hubs and drive through town and engage and disengage the transfer case into 4 hi and pop it out on dry pavement. Now in my 4 Runner with the locker how do I drive in town? Do I have to get out and lock hubs in every slippery spot? Or just hammer down clown.
Just drive slow and let the tires slip. Someone might have welded the diff?
when I unlock the hubs both tires spin Independent but when hubs are locked they both go the same direction.
Are you notice any wierd noise from your front differential after installing the locker?
well you should have clicking noises from the ratcheting for the locker but outside of that, no noises for me.
My Land Cruiser Prado 98 diesel has the H=High speed box (70% power in the rear, 30% in the front)
HL= High speed Lock Differential (50% rear, 50% forward)
LL= Low speed Lock Differential (for extreme conditions), is it possible to install front Spartan Locker?? physically it is the same as the 7.5 inch 4runner 3rd generation
I don’t see why not
I was about to install in the front a spartan locker on my Hi Lux 89 4 cyl IFS, single cab, and someone advice me that the locker eventually will brake the CV joints.
He told me that the spartan locker does not work well with IFS only with solid axle.
What do you think about that suggestion?
Thanks for any answers.
Cheers from latin america.
35" tires and below can use spartan. Any locker will break CV's up front. Just be extra careful.
@@PhoRunner Thanks pal, 👍👍💯.
Lsd or torsen up front works well
Put an Ebrake on 2 front wheels separately than stop the spinning wheel when offroading lol
Ok I got my spartan locker installed in my new junk yard 4.30 front diff just put it back in car I will try it out on the road after everything seems ok but for now it is on jackstands. First concern when i spin the driver tire it spins the driveshaft the passenger does not. When I put in 4wd everything seems to work ok. I have a 4.10 rear which I am swapping with a4.30 elocker soon I was going to drive my 4runner after getting the new front diff done just keeping it in 2wd but with the front drive wheel spinning the driveshaft i dont think i can drive it. Any thoughts? thanks again
4wd is controlled via the ADD system. It will lock to the passenger side. That’s why your passenger side isn’t spinning on jack stands. The Spartan locker only engages on load so you won’t see it locked up front on jack stand. Take it to dirt and try it out. You’ll hear some clicking on turns
@@PhoRunner thank for replying am I safe to drive in 2wd my front is 4.30 my rear is is 4.10?
@greenflintriver in 2wd, you will be fine. In 4wd, nope. Go slow and test though lmao. Don’t want you screwing anything up but logically, should be ok
@@PhoRunner thank you!
Hey sir at 1:11:08 you are installing a gear and you just drive it in with a rubber mallet are we supposed to remove the clip I couldn’t tell from the video but mine won’t go in with the clip on😢please advise thank you
Clip must stay on. Put a block of wood on top and use a bigger hammer. It’s a retaining clip so it can be a pain sometimes
@@PhoRunner This is my first time and you are a great resource! Thanks 😊
No problem!! It was also my first time in the video! Mines been running solid since!!! I also did a regear and it’s solid also!! Not rocket science but definitely requires some proper tools and techniques
Can you post a video how the spartan locker performs and engages on the IFS ? During 4x2 operations, how is it? TIA!
Yeah it's on my todo! Hard to find someone to film lol and time to go out. It just engages when you step on the gas with any load.
In 4x2, it doesn't do anything since 4WD ADD isn't engaged. You can drive all day long with it if it's up front like mine is. I drive home sometimes like this after using 4x4 even with the hubs locked.
@@PhoRunner does the front spartan locker click or make any noises in 4x2?
@@djrodriguez6582 I never hear it in 2wd even if my hubs are locked (stock 4runner).
@@PhoRunner i finally got mine installed and it works great offroad. im having a weird issue where the truck is pulling to the left in 2wd as if the drivers side wheel is still engaged. did you have any experience like this?
@@djrodriguez6582 No i don't have anything like this. I'm driving around with hubs locked and i don't experience any pulling. The diff is definitely spinning over on the driver side though as the CV spins the front diff. Maybe that extra load is causing the pulling? Have your alignment checked?
After 10 months how is it I want to do it to mine. Would you do it again or just get a air locker?
Yes! I think it’s a great budget option. I’ll be doing a little video about it in the future on what my thoughts are
I read you said it binds. Can you drive threw it or do you have to reverse or actually disengage 4wd to get past it ??
You can easily drive through it. I’ve gone all directions with it engaged on dirt and rock and to be honest it is just fine. I wouldn’t do it in the rear but definitely for the front.
Hey i have a 2000 sr5 if i add this to the front will it bind up in 2wd while turning?
No it will not bind until 4wd activated
@PhoRunner so I can trun in 4wd as long as I'm off road not on road right
@Cmc-365 yup. You’ll hear some ratcheting in 4wd. In 2wd, should then like stock.
Does it bind or oversteer with the front locker installed?
when 4wd is on, it binds and oversteers quite a bit!
Is it controllable?
@@saephan34 it is automatic so no.
My bad I was talking about the steering with engaged in 4wd
Your breaking fastners with a 12point?!
no. those are E14 and 6pt sockets. I never use 12 pts unless its for a head or taking off wheel locks ;)
just picked up a cherry 98 limited with locker looking to do this mod how has it held up over time?
Perfect!! It’s all working amazing still
Can't believe how much you're willing to not do on a project this size.
I would really be checking tolerances. That could mean the difference between having to take it apart again and not having to. Those springs unseat in your carrier, and that's gonna SUCK.
Been fine since!! I’ll be tearing it apart again for regear soon. I’ll be sure to check things when I do this
@@PhoRunner I'm glad to hear that it's been good. Great video! For me though, the audio cut out for the last chunk. Like probably 20ish minutes. Just a heads up.
Just hook another wrench on that wrench and get some Leverage
How do you engage the locker? or is it always locked? and if so how's the low speed cornering in 2wd?
Throttle locks it up. Since it’s in the front, you can daily it since the front isn’t locked at all until 4wd is engaged
are they on the way on the front, they are rattle like crazy
mine works great!!! it does ratchet but not too bad
@@PhoRunner should you suggest for me to install on my FJ60 rear?
I wouldn’t run these on the rear if it’s daily driven. It will ratchet a lot in city driving and may bind on turns
@@PhoRunner so on front it is OK?
Yeah since it won’t ratchet because passenger side will be free. Try to find an elocker axle and swap that baby in!
BAD JOB !!!!!!!!!!
