I saw that Eaton True Trac says not to use synthetic or friction modifier. That wouldn't be the deciding factor however. Could you use factory parts? What you think of the SPARTAN LOCKER SLF8831?Might want to look into a Eaton True Trac, The factory clutch type posi's are notorious for being worn smooth out from low preload on the side gears.
I Second the true trac. The Eaton fluid recommendation has been debated quite a bit, mine has Delvac 1 in it and does very well.
Ive heard good things about the Spartan locker but if you have a pinion noise as alluded to in the other thread, you might as well put a whole new differential rather than an lunchbox locker.
Synthetic lube is okay, I'm running Redline 75w90NS with my True Trac & it performs very well. Just don't run any LS additive of lube with LS additive, Mobil Delvac 1 is also a good recommendation.I saw that Eaton True Trac says not to use synthetic or friction modifier.

How soon do they wear out or how much is this a problem? Yeah, I understand it all depend how someone uses their vehicle. The reason I ask is because the vehicle is already 17 years old, doing about 5000 miles a year and hardly works heavily. If the OEM works just as good as True Trac, when it works, then I might opt to use OEM if it is much cheaper.Might want to look into a Eaton True Trac, The factory clutch type posi's are notorious for being worn smooth out from low preload on the side gears.
I like Torque Biasing posi's like the True-Trac & Torsen over Clutch Type & Cone Type posi's. Personnel preference of coarse.
In that case......The OE units are rebuildable. Then you have Cobra "S-Springs" to increase pre-load.
