2. CAUTION: If reusing the differential ring gear and pinion measure and record the backlash before disassembly. Re-assembling the differential
ring gear and pinion to the recorded backlash will match the established wear patterns. Hand rolled patterns will cover less area than the
established patterns.
Measure and record the differential ring gear and pinion backlash.
^
Check the backlash in four equally spaced positions around the differential ring gear.
^
The acceptable backlash tolerance is ± 0.0508 mm (0.002 inch) from the backlash etched in the differential ring gear.
^
The tooth contact pattern can move only by adjusting backlash. The tooth contact pattern can move only in the direction of heel-to-toe, and
toe-to-heel. Depth of the tooth contact pattern is not adjustable. Contact Spicer Service at 1-800-666-8688 for assistance if you are unable to
establish an acceptable tooth contact pattern within the limits of backlash.
3. Remove the rear anti-lock brake sensor.
4. Remove the adjusting ring locks.
