I Pulled my diff centre out of my 89' LJ71 cruiser ( with stock 8" diff's ) last weekend as it was leaking & have to put a new wheel bearing kit in one side , when i pulled the diff centre , was kinda stumped/not sure as its been workn as an Open diff ( was lookn for a LSD for it ) , yet it looks like an LSD carrier , unless it is & the clutch's are stuffed .

Is this a LSD Carrier or Open Carrier ???

hard to tell from that view, if its an open diff, may have to turn the internals a bit to see better, it might have a larger window where ya can see the spider gears quite clearly...

lsd may be like 'as in picture' the entire way around.. :wink:

well, me thinks anyway.. :roll:

dunno much about 8" diffs but the book shows it as a LSD, you can visably see the pinion and side gears inside the carrier housing on the std open diffs.

got to be a LSD :wink:

*EDIT
there is a 4 pinion open diff that has a carrier housing like that in the book as well so I dont know any longer :scratch:

looks rather like a 4 pinion open to me
(you can see the spider gears through the hole, lsd you can see the clutch pack)

this is a 2 pinion open

4cyl Turbo and V6* 4Runners and mini-trucks use the Toyota 8" 4-pinion differential in the rear. This diff is known as the "V6/Turbo diff." It has larger carrier bearings, is generally stronger than the standard 4cyl version, and is a direct swap into axles that use the 4cyl 8" diff. Separate gear sets are made for the V6 style diff (only from Toyota and Precision Gear), but cheaper, more readily available 4cyl style gears are commonly made to fit- the only difference being a very slightly larger pinion gear on the V6 style gear (the actual strength difference in gear sets is debatable). The strength increase in this diff over the 4cyl diff comes mainly from the beefed up housing, which stiffens the entire assembly, keeping the gears in proper (stronger) alignment.

Although somewhat rare, there is a version of this diff that came from the factory with 4.88 gears. The carrier (3rd member housing) has a different pinion offset so that the ring gear doesn't need to be as thick. This means that no gears other than the factory 4.88's will fit this particular diff. However, diff cases, commonly called carriers (factory, LSD, lockers, etc.), for the standard V6/Turbo diff should be interchangeable (4cyl and V6/Turbo carriers are NOT interchangeable).

* A few V6 trucks and 4runners have been found to have come with the 4cyl style diff from the factory. Nobody knows why.
Ten 10mm ring gear bolts, 27 spline pinion shaft.

Yep, definitely the std 4 pinion open, had mine out a while back.

Cheers
