Ring and pinion gears are matched sets. When replacement
of one or the other is necessary, both the ring and pinion gear must be replaced.
| • | Check the pinion and ring gear teeth for cracking, chipping, scoring,
or excessive wear. |
| • | Check the pinion gear splines for wear. |
| • | Check the pinion flange/yoke splines for wear. |
| • | Check the fit of the pinion gear splines on the pinion flange/yoke. |
| • | Check the sealing surface of the pinion flange/yoke for nicks,
burrs or rough tool marks that could damage the seal and cause an oil leak. |
| • | Check for worn or broken parts and replace as necessary. |
