2008 Cadillac SRX Differential Seal

You should install the drain plug to the Differential, clean any dirt from around the differential fill plug, remove the fill plug from the differential, fill the differential with 75W90 synthetic axle lubricant, GM P/N 12378261 (Canadian P/N 10953455) or equivalent, inspect the gear lubricant level to ensure it is even with the bottom of the fill plug hole to no lower than 6 mm (0.25 in) below the opening, install the fill plug to the differential and lower the vehicle.

It occurs when driving the vehicle at various speeds a squeaking sound occurs. If one or more of the universal joints have lost lubricant, you should replace the Driveshaft completely and if the C/V boot is worn or torn, you should also replace the driveshaft completely.
