Carefully pry the cover off to avoid damaging the gasket.
Clean the mating surfaces on the differential housing and cover.

4. Inspect Differential Components

Inspect the gears and bearings for signs of wear or damage.
Check the ring and pinion gears for proper alignment and any signs of scoring.
Replace any worn or damaged components as necessary.

5. Reassemble Differential

Install a new gasket or reapply sealant to the differential cover.
Reattach the differential cover and torque the bolts to the manufacturer’s specification (typically around 30-40 ft-lbs).
Refill the differential with the manufacturer-recommended fluid type and quantity.
