my owners manual for my 99' xj sport says that i should run 75W-140 in the rear axle because i have a class III towing package, but says nothing about the front other than running 75W-90 if you dont have the tow package. so do u think i should run 75W-90 in the front or 75W-140? Also i dont think i do but how do u know for sure if you have Trac-Loc or not? it requests a limited slip additive. i do moderate offroading but nothing intense but i want to run the best fluid i can. i was thinking about royal purple synthetics, what do u guys think?
