NOTE:
-
Tooth contact pattern is a method for judging the result of the adjustment of drive pinion height and final drive gear backlash. The
adjustment of drive pinion height and final drive gear backlash should be repeated until the tooth contact patterns are similar to the
standard tooth contact pattern.
-
When you cannot obtain a correct pattern, the drive gear and drive pinion have exceeded their limits. Both gears should be replaced as a
set.
5. Check the oil seal for wear or damage.
6. Check the bearings for wear or discoloration.
7. Check the gear carrier for cracks.
8. Check the drive pinion and drive gear for wear or cracks.
9. Check the side gears, pinion gears and pinion shaft for wear or damage.
10. Check the side gear spline for wear or damage.
