REAR-REAR AXLE DIFFERENTIAL - CONTINUED
ASSEMBLY - CONTINUED
The final check of the differential assembly is checking the gear tooth contact by paint impression method. When
the ring is turned, the applied paint is squeezed away by the contact of the teeth, leaving bare spots the exact size,
shape, and location of the contacts.
When making adjustment, check drive side of gear teeth. Coast side should be correct when drive side is correct.
With all adjustments properly made, the result is a quiet running ring gear and pinion gear because the load is
evenly distributed over all teeth.
Ring gear (2) a.
Apply oiled red lead paint lightly to
12 gear teeth.
Turn gear (2) one complete turn.
Sharper impressions can be made by
applying some resistance to gear
with a pry bar and using an open-end
wrench to turn pinion gear.
