Reassembly When reassembling the differential, the flanges of the case, ring gear pilot and the back of the ring gear must be clean and free from burrs.

Lift off the case cover and remove the differential gears and pinions. The ring gear may be removed from the right-hand side of the case by tapping it with a soft-faced hammer. Inspection Wash all parts thoroughly in clean gasoline or cleaning solvent. Check all gears for chipped, cracked or scored teeth. Inspect the differential side gear and pinion thrust surfaces in the housing halves for wear or score marks. Check the fit of the side gear hubs in the differential case halves. The fit of the pinions should be checked on the spider. The differential side bearings should be carefully inspected for worn, checked, scored or broken rollers. They should then be oiled and rotated by hand to check for roughness. Any damaged or worn parts should be replaced.
