TOOTH CONTACT
After backlash adjustment and left side shim selection are car-
ried out, the tooth contact must be checked. Pay attention to the
following points:
• Remove the front drive train (differential) gear assembly.
• Clean and degrease several teeth on the ring gear and drive
bevel gear, and then apply a coating of machinist’s layout dye
or paste to several teeth of the drive bevel gear.
• Install the removed left and right side shim(s) and front drive
train (differential) gear assembly.
• Assemble the gear case cover. (

• Rotate the front drive train (differential) gear several turns in
each direction. This will provide a contact pattern on the
coated teeth of ring gear.
• Remove the front drive train (differential) gear and compare
the coated teeth to the examples shown in

the shim must be changed and the tooth contact should be re-
checked until correct (example
