Just picked up my 2001 grand cherokee 2001 year.
It needs a real good service all fluids replaced.
oil i can get 5w30 in england but not sure about where to get the high zinc oil?
auto box fluid i can get some comma branded fluid which is mopar atf4 + rated.
gearbox i can get castrol syntrax limited slip 75w 140 oil or i can get plain oil and limited slip additive:
RED LINE Limited-Slip Differential Friction Modifier / Break-in Additive
are these products suitable, for a jeep grand cherokee on 115k miles?
