Turn the pinion gear for one revolution [B] back and forth,
while creating a drag on the ring gear hub [C].
Remove the ring gear assy and pinion gear assy to check
the drive pattern and coast pattern of the bevel gear teeth.
The tooth contact patterns of both (drive and coast) sides
should be centrally located between the top and bottom
of the tooth. The drive pattern can be a little closer to the
toe and the coast pattern can be a somewhat longer and
closer to the toe.
If the tooth contact pattern is incorrect, replace the pinion
gear shim(s), following the examples shown. Then erase
the tooth contact patterns, and check them again. Also
check the backlash every time the shim(s) are replaced.
Repeat the shim change procedure as necessary.
If the backlash is out of the standard range after
changing the pinion gear shim(s), replace the ring gear
shim(s) to correct the backlash before checking the
tooth contact pattern.
