my rear diff on my 2005 ford mustang is making a whine and popping sound no loss of power or vibration any ideas?


The first step regardless of differential type should be to check the fluid level and condition. If this is a limited slip differential, the whine and popping may be coming from the clutch pack. Check, drain, and refill the differential with the appropriate amount of fluid and limited slip additive (if required), and inspect the internal components for damage or wear.
