More than 35 % red lead contact area on the gear tooth surface.
The center of tooth contact at 1/3 of the entire width from the small
end.
Replace the adjusting shim (2) with thicker one to move the
spiral bevel pinion shaft backward.
For move the spiral bevel gear rightward, reduce right side shim
(5) and add shim (6) of the same thickness as the right side to left
side.
Replace the shim (5) with a thinner one to move the spiral bevel
pinion shaft forward.
For move the spiral bevel gear leftward, reduce left side shim (6)
and add shim (5) of the same thickness as the left side to right side.
Repeat above until the proper tooth contact and backlash are
achieved.

Clearance between Differential Case Bore (Differential Case
Cover Bore) and Differential Side Gear Boss
1. Measure the bore I.D. of the differential case and differential
case cover.
2. Measure the differential side gear boss O.D. and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace them.
