Procedure J - Ring and Pinion Vibration

Differential:

1. Remove differential cover or carrier as necessary.

2. Measure ring gear runout. If excessive, remove ring gear from carrier.

Specification: 0.07 mm (0.0028 in.)

3. Measure differential carrier runout at the ring gear mounting face. Also, check for any foreign material or burrs which may have prevented ring gear from seating correctly.

4. If differential carrier runout is within specification, replace ring and pinion. If differential carrier runout is the cause of excessive ring gear runout, replace carrier assembly. Recheck vibration.

Specification: 0.07 mm (0.0028 in.)

Ring Gear:

5. If ring gear runout is within specification, check ring gear backlash. If ring gear backlash is not within specification, adjust as necessary.

Specification: 0.13-0.18 mm (0.0051-0.0071 in.)

6. Recheck ring gear backlash at every tooth on ring gear. If ring gear backlash variation is excessive, replace ring and pinion.

Specification: 0.1 mm (0.004 in.)
