- Remove plugs from the differential housing and vacuum fluid from the carrier housing. Flush the housing to remove debris and dry all internal components. Install an endoscope and check all internal components for excessive wear. Found that the inner pinion bearing was faulty and the source of the noise. It is recommended that the carrier bearing and also pinion bearings ne replaced. Remove drive shaft, yoke, and support bracket to access the pinion seal. Remove the old seal assembly and deflector, Clean the yoke and housing bore and polish the sealing surface of the yoke. Replace all of the carrier bearing and both pinion bearings and set the proper preload on all replaced components. Install the new seal, lubricate the seal lip and reassemble the yoke assembly. Adjust the pinion turning torque and reassemble the carrier components. Add fluid to capacity and additive if necessary. Road test vehicle and recheck fluid levels and check for leaks.
