Differential service is best left to those extremely familiar with their vagaries and idiosyncrasies. A great many specialized tools are required as well as a good deal of experience.
REMOVAL & INSTALLATION
- Raise the vehicle and support it safely with jackstands.
- Remove the differential drain plug and drain the lubricant from the differential. Install the plug after all of the fluid has drained.
- Remove the axle shafts as previously outlined.
- Remove the driveshaft(s) as previously outlined.
- Remove the carrier-to-differential housing retaining fasteners and remove the carrier assembly from the housing.
- Clean the carrier and axle housing mating surfaces.
- If the differential originally used a gasket between the carrier and the differential housing, replace the gasket. If the unit had no gasket, apply a thin film of oil-resistant silicone sealer to the mating surfaces of both the carrier and the housing and allow the sealer to set according to the manufacturer's instructions.
- Place the carrier assembly onto the housing and install the carrier-to-housing fasteners. Torque the fasteners to 12-17 ft. lbs.
- Install the driveshaft(s) and axle shafts as previously outlined.
- Install the brake drums and wheels.
- Fill the differential with the proper amount of SAE 80W-90 fluid (see the Capacities Chart).
