Remove the front wheels.

Blocking the front wheels is essential for safety to prevent the vehicle from rolling while working on the rear axle.

After removing the wheel and brake drum or disc, you should remove the cover from the differential carrier and allow the lubricant to drain into a container.

The rear axle assembly in most models is a hypoid, semi-floating type.

For installation, pry off the old spring clip from the inner end of the driveaxle and replace it. Apply grease, insert the splined end of the inner CV joint into the differential, ensuring the spring clip locks in place. Apply grease to the outer CV joint splines, insert the outer end of the driveaxle into the hub, and connect the lower control arm and toe link to the knuckle, tightening the fasteners.

The axleshafts are splined to the differential side gears.

To complete the front driveaxle removal, remove the steering knuckle, and then remove the driveaxle assembly.

Disconnect the vent hose.

The manufacturer recommends using a new pinion shaft lock bolt for installation. However, if one is not available, you should coat the threads with a non-hardening thread locking compound.

On 4WD models, remove the rear spring spacers while lowering the axle.
