Pinion and Ring Gear

NOTE: Ring and pinion gears are matched sets and both are replaced any time a replacement of either is necessary.

Inspect
- Pinion and ring gear teeth for cracking, chipping, scoring, or excessive wear.
- Pinion gear splines for wear.
- Pinion flange splines for wear.
- The fit of the pinion gear splines on the pinion flange.
- The sealing surface of the pinion flange for nicks, burrs, or rough tool marks that could cause damage to the inside diameter of the seal and result in an oil leak.
- All worn or broken parts and replace if necessary.
