Well. My 2004 Rubi did in the rear. Thats why the manual says you have to use the friction modified posi gear oil in the rear. Also it is described in the owners manual which I still have.Clutch Posi rear with lockers off. Plus air locking front and rear. Also it is all shown in the shop manual for 2004 as well. And I have checked it out when doing fluid changes. Later

You seem to be confusing the Trac-Lok with the TRU-LOK in the manuals.

TRU-LOK is the rubicon axle and trac- lok were in dana 44s in other tjs also

TRU-LOK rear diff has an excellent gear driven torsen type limited slip, front has no LS

TRAC-LOC rear diff has an OK conventional clutch pack limited slip

The service manual covers both and they overlap at points making it difficult to discern the two at points since most everything service wise is the same.

Friction modifier not required either. But 75/140 typically has it anyway and it doesn't hurt anything.
