There is a Toyota dealership selling the TRD limited slip diffs for $240 on ebay.

I purchased one from them. Nice people, great price.
BTW, it's the EATON LSD. Very beefy!
I put one in my Tundra and the other is going in my T100.

 

They don't list the 3 gen 4runners. Don't the have the same rear diffs as the tacomas?
I have a '97 runner (V6) and would love something like that.
Would it fit?

No, the 4Runner's have a smaller 8" ring gear. The Tacos, Tundras and T100's have 8.4" ring gears. No TRD LSD Luvin' for us 3rd Gens...

Peace.

Too bad, I don't do though offroading, but some extra traction would be sometimes be nice. Our town is on a hill and when it rains (often here in southwestern BC) one wheel looses traction and you start spinning a wheel up the hill trying to take off from the light. A lsd would be ideal in those situations.

 

Tractech makes an LSD that fits our trucks. It's called the Trutrac. Call DriveTrain Direct or West Coast Differentials for some prices and applications.

Good luck

I'm helping a friend install a tru-trac in the front of his 87 PU (7.5").

 

When installing this LSD you have to set the gears and everything, right? It's not just a drop in?

 

You do have to set the gears. (maybe)

I put mine in on saturday. I was prepared to set the gears but the TRD diff is made to about the same spec as the open carrier and it was perfect the way it was. Backlash was in spec and the pattern was excellent.
If you are going to do it yourself you need a press and gear puller, torque wrench, loctite, gear marking compound, and a very clean work area, in addition to the standard hand tools.

Also, get some shims in case you aren't as lucky as I was. Unlike most toy diffs which have adjuster wheels, the 8.25 in tundras, tacos, and T100s takes shims to set the side to side carrier adjustment. Fortunately the shims are on the outside of the races so it is easy to try different sizes if neccesary.

I've had 2 TRD LSs and wouldn't really recommend them. When new they were very tight and hard to quiet down. Then they were utterly worn out in 40k miles. I've used a couple of Trutracs and love them. Smooth, quiet, positive, and I don't think you can wear one out. Just my 2cents.

 

Trutracs don't so much wear out as explode and wipe out gears and bearings.(under extreme use) Do you know if the TRD is rebuildable??
