Suggestions on front and rear diff fluids. Also, what additives for rear? T case and the motor oil too.

thanks

 

If you have the money you cant go wrong with Royal Purple. No additives are required for the rear with it.

 

Front/rear and t-case use any 80wt, 90wt or 75w-90wt gear oil. If the rear is a limited slip, then use 'I think' 8 ounces of limited slip additive. Check owners manual, do a search or maybe someone can chime in. Any 15w40 will work fine for the engine.
