Cleaning and Inspection
Clean all parts in solvent. Allow bearings to air dry.
Dry other parts with compressed air.
Inspect the differential bearing cones, cups, and roll
ers for pitting, galling, flat spots, or cracks.
Inspect the differential case for an elongated or en
larged pinion mate shaft hole. The machined thrust
washer surface areas and counterbores must be smooth
and free of nicks, gouges, cracks, or burrs. Inspect the
differential case for cracks or other visible damage
which would necessitate replacement.
Inspect the pinion mate shaft for excessive wear in the
contact area of the differential pinions. The shaft should
be smooth and concentric and not scored or galled.
Inspect the differential side gears and pinions; they
should have smooth teeth with a uniform contact pat
tern but not display excessive wear or broken surfaces.
The side gear and pinion thrust washers should be
smooth and free from any scoring or metal pickup.
Inspect the pinion mate shaft lockpin for damage or
looseness in the case. Replace the pin or case as
necessary.
Inspect the ring and pinion gears for worn or chipped
teeth or damaged attaching bolt threads. If replacement
is necessary, replace the ring gear and pinion as a
matched set only.
