2007 Buick Rainier Differential Pinion Bearing

You should install the outer pinion bearing cup, and the inner pinion bearing cup, determine the selective shim thickness for the pinion, install the selective shim between the inner pinion bearing and the shoulder on the gear, a new collapsible spacer, the pinion into the axle housing, the outer pinion bearing onto the pinion, a new pinion oil seal, the pinion yoke, the washer, and a new pinion nut, the J 8614-01 onto the pinion yoke as shown, and the differential.

You should remove the differential, the drive pinion from the axle, install the J 45871around the pinion bearing and the J 22912-B in the inverted position around the J 45871, remove the shim, the outer pinion bearing cup from the axle housing using a hammer and a brass drift in the slots provided. Move the drift back and forth between one side of the cup and the other to work the cups out of the housing evenly, and the inner pinion bearing cup from the axle housing.

You should install a new pinion oil seal using the J 33782, 8.0 inch axle or the J 38694 8.6 inch axle, the pinion yoke, seat the pinion yoke onto the pinion shaft by tapping it with a soft-faced hammer until a few pinion shaft threads show through the yoke, the washer, and a new pinion nut, the J 8614-01 onto the pinion yoke as shown, the propeller shaft, the brake rotors, the brake calipers, and the tire and wheel assemblies.

You should remove the tire and wheel assemblies, the rear brake calipers, the brake rotors, and the propeller shaft, install the J 8614-01 as shown, remove the pinion nut while holding the J 8614-01, the washer, the J 8614-3 and the J 8614-2 into the J 8614-01 as shown, the pinion yoke by turning the J 8614-3 clockwise while holding the J 8614-01, and the pinion oil seal.
