I just removed my ARB from the front axle. Had to cause I swapped it for a 2JZ engine and I seldom use the ARB.
I wanted to retrofit the OEM open carrier (Landcruiser 70-80 series high pinion) but discoverd that I have 3 allmost identical carriers in my shed.
I recall stripping 2 supra's, an '86 7M-GE auto (with optional LSD package) and a '92 7M-GTE manual. Plus I have the LC open carrier from the high pinion.
I can identify one set as from a supra cause it had the 3.7 gears. This is also the LSD which is 5mm smaller than the other 2 LSD's. Dunno if its from the turbo or not.
So I'm left with 2 identical carriers with identical dimensions and bearings. They are so identical that I cannot see which one is the LSD and which one is the open model. I have to open one up or use 2 shafts to find out which is the lSD.
Since they are the same I have a choise. LSD or not?

Now back to my question: is it worth to have an LSD up front?
Anybody use a supra LSD up front before?

WHAT? A 2JZ in a 4Runner? Is it a 2JZ-GE or 2JZ-GTE?

From a certain movie: "2JZ...NO ลลลล!"

Pics?

I have an LSD up front. It's A Detroit TrueTrac. I believe it is worth it. Certainly better than open.

Depends on what kind of 4wd use your truck gets more than anything \else.

I have limited slip in the front of my truck, and it is a lot better than open for what I do.

haha open axles suck....i know from experience. go for the lsd

superjoe83

if you have the LSD then put it in, but from my experience they don't do much for anything but mild wheeling, IMO a limited slip belongs on road, not off

and lsd is not as good as a locker, but is a lot better than an open diff

Okay, I think I will give it a try. Maybe even add some shims to the LSD for more (less?) slip.

No pics of the engine yet, I will probably pick it up in a week or 2.
It's a 2JZ-GE so no turbo. That would be a bad idea cause the 4R is lifted and kinda heavy due to the xtra's. If I drive the 4R (with the 7M-GE) hard, my brakes start to fade after 4-5 corners and my passengers go

If I wanted to go 'twinturbo' fast I would get another vehicle like a stock supra, this is still my wife's DD.
I do have a suzuki which I want to build up with yota parts and what will become my weekend warrior. Unfortunately all my effort, parts and money seem to go to the 4R. I wonder why.

yes very very very true....thats why i wish i had one sometimes...lets just say with an open diff, gravel and a heavy foot never turn out great....

ahhh lsd in the rear on road isnt that great either in a pickup due to side stepping.....i learn to hate it in my s10.....

Update:
I had to mount the open carrier. The carrierbearings of the supra are 50 x 83 x 24mm. The high pinion housing uses the smaller 45 x 80 x 21 bearings.
Since I did not have the proper bearings I unfortunately had to put it back together with the open carrier.
Which I allready mounted in my other 4R rear axle for my suzuki project. So I had to strip that too, remove the third member and take out the carrier.
So what looked like a simple thing turned into a battlefield again. My garage looks like a got bombed, diff parts and grease everywhere.

The 4R is up and running now so I only have to put back together the other third member and axle.

I'm sure it would work with the proper bearings but I'm not going to try that anytime soon.
