Since my car not running right now, Im order some royal purple tranny and rear differential fluid.
1. its ok to use Royal Purple Max Gear 75w90 Gear Oil on my 1998 gt ? hayness manual say I should use SAE 80W-90GL fluid.
2. I went to ford dealer and asking for gasket for my rear diff, they told me that I should use some grey silicon, cause they dont make gasket for my car, what should I do now, I really want to use gasket with grey silicon. and where can I buy the gasket ?
3. Should I use locktie on all the bolt include fill bolt ?
4. What kind of rear diff i had ?
thanks
