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.
