Pinion and Ring Gear Inspection for Cadillac Escalade EXT 2002
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. |
