57.
Remove eight screws (4), washers (5), mainshaft (3), and shim pack (2) from differential carrier
housing (1).
NOTE
If adjustment is needed to correct bevel ring gear and pinion gear
contact pattern, make initial shim changes of at least 0.010 in.
(0.25 mm).
For contact pattern of type in step 50, add shims to shim pack (2) and remove shims from shim

Check bevel ring gear (18) and pinion gear (19) backlash (20) using dial indicator.
63.
Backlash (20) should be 0.005-0.015 in. (0.127-0.381 mm).
NOTE
If backlash needs correction, refer to steps 54, 55, 56, and 57.
If bevel ring gear and pinion gear backlash is within limits, go to
step 70.
If bevel ring gear and pinion gear backlash is not within limits,
go to steps 64 and 65.
If backlash (20) is less than limits, add equal amounts of shims to shim packs (2) and (12).
64.
If backlash (20) is greater than limits, remove equal amounts of shims from shim packs (2) and (12).
