Important
• Anytime a differential pinion shaft locking screw is
removed, it is important to coat the screw threads
with Loctite 242 before reinstalling. These screws

the screw from loosening in the case. When this
'No-

PATTERN CHECK
Checking the ring gear to pinion tooth pattern is done
only after setting up the axle according to the methods
in this section. The pattern check is NEVER used as an
initial check, or instead of checking pinion depth and
backlash adjustments. This check is only used to verify
the correct adjustment of the gear set after setup.
1. Wipe all oil out of the axle housing, and carefully
clean each tooth of the ring gear (figure 26).
