I don't feel like going into detail right now; however, be advised that the EATON PN 19614-010 LSD unit is NOT the correct part for the 2002 4Runner Limited. More later.

 

Peter, I feel your pain.....that is just rotten.

As far as tires the less weight the tire takes when balancing, the better the manufacturing quality (doesn't necessarily mean it will not perform any better). As long as they were road force balanced, you shouldn't have any issues. You should also be able to put a P265/70R16 on a 16x8.5 rim (it should fit 16x7.0 to 16x9.5 sometimes 16x10.0). You have a pic of the rims you were hoping to get?

Things are going very well here too, busy as heck, but smooth sailing.

 

Pain is not the word for what I am feeling right now. EATON has yet to contact me to discuss this, shall we say face to face. I emailed my OEM parts guy to see if I can get a Toyota LSD.

As for the wheels, I know my tires will fit on the TRD rims but I wanted something wider that would still have the same diameter. The rims are the IVAN STEWART TRD Tundra/Tacoma rims and I can get them for $189.00 each from Rusty Wallace Toyota.

Did you end up with or do they only have one for the 8" 4cyl diff? You diff is the same old V6 8" diff as the earlier years. ARB RD23 goes in it for reference.

Any reason why you don't want the Detroit Tru-Track? Don't really know much about LSD's. Just hard lockers.

 

Steve,
I am not familiar with the units you are speaking about. They asked me if my 4Runner was a 4 or 6 cylinder and when I answered "6" they seemed very confident all would be well. However there are so many differences it is ridiculous. The collar is longer and the axle splines are recessed deeper. The difference is about 1/4". I really do not know much about the variations but this is what I recall from speaking with my mechanic while he was reassembling the rearend.

 

Funny you mention those.....I debated getting those rims, but they are just a bit more than I wanted to throw into another set of rims. Those things look sharp though!!!

As for tires I think the widest you can go with a 16" rim would be these (they are same diameter as P265/70R16s):

I am not sure those are the greatest tire either.

If you really wanted to go significantly wider, the best way is to go with bigger rim diameters and lower profile tires. Some 17" or 18" rims would look great and you can go all the way up to 20" without looking too cheesy (IMHO) and the selection of wide tires goes up exponentially from there. A friend of mine has some 20" on his 4runner and they looked very sharp, but it is all personal opinion.

 

Well-

Here you go:

I know quite a few people have these in the front diffs that have rear e-lockers as the unit is only $300 which is about 1/4 of the cost of an ARB with a compressor.

Here is the info on it:

Here is the application guide:

You just want more traction on the street, right?

If you want a Detroit True Trac Limited Slip this most certainly does fit.

Part: 813A028

The way you know it does is that it crosses over to the FJ-80 and FZJ-80 front diff which is a V6 8" as well. All of the correct models are crossing over. Which means these people know what the difference between a V6 8" diff and a 4 Cyl 8" diff is.

Good luck doood.

 

Hey here is another idea for you. Why don't you try to find a 2nd 3rd Gen rear diff that has the same gear ratio as you. Set that up ahead of time and then when you know it's all set up and ready to go, just swap diffs.

Since the install will be out of the truck, you will know for sure before hand everything is fine.

For example I have three diffs for my 1981 truck. I can have one set up while the stockers are still in the alxes. Then just swap in the new one and it's done. I also would not mind picking up a couple of V6 diffs as well.

 

THIS IS A RE-POST OF A NEW THREAD POST I JUST MADE IN HOPES OF SAVING OTHERS FROM MY EXPERIENCE.

If you have any interest in a LIMITED SLIP DIFFERENTIAL for your 4Runner, this is a must read.

I have been running a thread titled EATON LSD for 2002 4Runners. I have had an EATON LSD unit on order for about a year and finally received it this week. I am always skeptical about after market performance parts. Therefore, I do extensive research and direct inquiries with manufactures because I am fearful that I will be an extension of inadequate R&D and something will go wrong or not as represented. I was assured by two engineers at EATON TORQUE CONTROL that PN 19614-010 would fit without any modifications, shimming, etc.

After taking the rear end completely apart, the side bearings did not transfer onto the new cage and the difference was about .04 - .05 too big, plus the height was about ¼ inch too high on the new unit. I won’t bore you with any of the back and forth vain attempts between EATON and my mechanic to figure this out, but the end result was that my differential is back in its original assembled condition and the EATON LSD is being returned to the Mfg.

The unit referenced above was intended for the TRD pickup trucks and it was “assumed” that it would fit the ’96–’02 4Runner. To add to the misery you and I may experience, PERFORMANCE PRODUCTS is inaccurately advertising (what else is new) a TRD “manufactured” LSD unit for all ’84–’02 4Runners. That unit is made by EATON and it will not fit. EATON also used to make the LSD units for Toyota but they do very little for Toyota these days and Toyota does not offer an LSD unit for our 4Runners.

EATON has just purchased Tractech Inc and they recommended that I might look into an LSD from them http://www.tractech.com/Products.htm#slip or an ARB RD23 from Drive Train Specialists http://www.drivetrainspecialists.com...duct-2394.html. I am not sure I am going to pursue this any further so I do not know if there is even an application for our 4Runners. EATON is not going to make any revisions or manufacture a unit for our trucks because we are an expiring niche market.

EATON has been very gracious and has taken responsibility for all the inconvenience and hardship they have caused me. I hope this information saves you from what I have gone through.

 

I would imagine what you had there was a limited slip for the NON-TRD Tacoma, which is an 8.4", the TRD Tacoma, would have an e-locker and be 8".

Ahhhhhh, this now makes sence. No 8" since the TRD Tacoma has the e-lockler, So they make the 8.4 for the Non-E_Locker Tacoma.

Sucks.

 

Steve,
This is one of the emails I received from EATON when we were trying to figure out what bearings to use. The bearings referenced in their info are the same size I already had on the OEM open unit.

2002 Toyota 4-runner
Axle Size 8.0"
Eaton LSD Part number ED-19614-010
Cone/Cup (Bearing/Bearing Race) Number:
(2 each) JLM104948
LM104912

 

Pertty much until you heard the words "Tacoma" you had no clue what they were working with.

If the only Tacoma's that have 8" diffs already have e-lockers, the only thing left is the 8.4".

Also the e-locker "pig" the metal casting is different and fits in a completely different houseing.

I don't fault you. It sure sounded like they made an 8" LSD, the fact that the bearings were too small confirms the unit was for a Tacoma 8.4" rear end.

Which is an ARB RD89 (8.4) The ARB RD23 is for the (8.0 V6) which is what 3rd Gens have. There is also an (8.0 4cyl).



The True Track will fit. No worries.

 

That sucks... Next time I'd ask what to get on here and not the company.
Tru-Trac, for the 8"

everyone here knows of the 8.4 and 8" differences in the Tacoma TRD/nonTRD axles
They should just give you a free tru-trac (or big discount) after they made you wait a year.

 

Steve, are these all tried and tested in 3rd gens already?
So if someone ordered them they would know it would fit a 4WD, V6, 8", rear?

I like the idea of a limited slip, but being in Canada makes it even more critical I get the right part the first time around.

 

Yeah, just get the True-Track one that cross refereces the FZJ-80 front. Which is the same as the 2nd Gen 3.0 motor rear and ALL 3rd Gen rears which is V6 8".

People "think" that Tacomas and 3rd Gen 4Runners are more the same than they really are. Here is something for you. Yes both vehiles take the same front shocks, but did you know the upper bolt holes on the tacoma are oriented so that one of the bolts is at the farthest out position on the top bracket, the 3rd Gen 4Runner has this pattern rotated 15 degrees. forward. Same shock, but top plate is rotated.

There are alot of other differences................

 

This is where it tipped me off.

1. You can not install this unit in a TRD Tacoma. It has an E-Locker houseing with the notch cut out. It also has an e-locker carrier with one huge bearing and one small bearing. It also has an e-locker.

2. So since it would be physically impossible to install a standard 8" carrier in a TRD Tacoma. They must have targeted the NON-TRD Tacoma. Which all have open diffs and 8.4" rear ends. A unit like this would fit perfectly and make sence as an application.

3. 3rd Gen 4Runners that HAVE the e-locker have V6 8" rear ends. 3rd Gen 4Runners that DO NOT have an e-locker also have V6 8" rear ends.

4. A 2002 non e-locker Tacoma and a 2002 non e-locker 3rd Gen 4Runner have DIFFERENT rear diffs.

I cut my truck up and rebuilt it, I know this stuff.

 

Has anyone found a solution for this? I was seriously considering the TRD LSD for my 2002 4Runner and I'm glad I saw this thread and learned it would not fit as PP claims.

Is anyone using the True-Trac? I had a Lock-Rite in my 97' Tacoma and hated it. It popped and clicked and lurched in turns. I'd like to hear experiences with the True-Trac to make sure it's not the same.

I hate the way the VSC works in this 4Runner and would love to have some traction aid device to help keep it from activating.

 

I have a True-Trac in my 98 Tacoma. It works quite well and I have never heard it. It is a gear based LSD so no worries about clutches wearing out. I recenlty put a SC on my 2000 4runner and that will be the next mod for it for sure.

 

don't bother with LSD's or lunchbox lockers....get a detroit, arb or elocker and be done with it.

 

Is your Truetrac an Eaton or Detroit? I've seen a member post on here that he's gone through 3 Eaton Truetracs as the gears are sheering. Some have said that since Eaton took over that the QA has gone down.

Also, how do you like your PP progressive springs? I'm looking to improve the ride quality on my 2002 4Runner and was considering these, however I don't want a harsh ride, just more firm with less body roll. I also wanna fit 265/75s.

As for getting an E-locker or ARB, I don't need that much beef. My 4Runner won't see any off road use. Been there done that and learned it's not for daily drivers.
