3B-35 Differential: Rear

Tooth Contact Pattern

Diagnosis and Remedy

Normal

High Contact
Pinion is positioned too far from the center of drive
bevel gear (1).
• Increase thickness of pinion (2) height adjusting

shim and position pinion closer to gear center.

• Adjust drive bevel gear backlash to specification.

Low Contact
Pinion is positioned too close to the center of drive
bevel gear (1).
• Decrease thickness of pinion (2) height adjusting

shim and position pinion farther from gear center.

• Adjust drive bevel gear backlash to specification.

If adjustment is impossible, replace differential carrier.

• Check seating of bevel gear or differential case. (Check bevel

gear for runout.)

• If adjustment is impossible, replace drive bevel gear and pinion

set or differential carrier.

Replace drive bevel gear and pinion set or differential case.
