it has a slight whine from the differential under aceleration,it also chatters or "grinds" on a sharp low speed turn (left or right).
i assume it has a "limited slip" being a 4x4,but what would cause this? i checked oil level and its okay, would a heavier oil and a couple of bottles of friction modifier help? is it the limited slip not releasing ? i don't know much about the limited slip rears and how they work:dontknow: THIA
