    Need help/advice in choosing rear diff fluid.

    I'm about to put a No-Slip locker in her (non-trd:().

    What diff fluid should I go with, considering I will now be running an automatic locker?

    Do I need to run some "additives" like LSDs?

    How many qts? (three?...from what I've been reading)

    Mobil 1 LS 75w90?
    Royal Purple 75w90?

    PS...also, will I be needing a new gasket for the third or just use some gasket sealer at the auto chain stores?

    No-Slips could vary depending on the manufacturer of the unit.

    Call the company directly and ask them what type of oil they recommend and if you need additives.

    im using amsoil 75w90 in my rear end. and if yours chatters, you can just add some additive until it goes away.

    the fsm says to use hypoid gear oil API GL-5 You will need 3 quarts
    2WD: 2.75L (2.91q)
    4WD: w/o diff lock is 2.45L (2.59q)
    w/ diff lock is 2.75L (2.91q)

    upon thinking about which fluid visocity to put in.......

    should i just buy the "regular" diff fluid instead of the "sythetic" for the initial "break-in" period of the locker once installed, or go all out sythetic the first time around?



    ^^^i'm gonna go with 80w90 because of the bitch-ass cold winters here.
