Position the differential pinion shaft through the case and pinion gears, aligning the hole in the shaft with the lock-bolt hole. Apply thread locking compound to the lock-bolt, install the bolt, and tighten it to the torque specifications.

Do not tap on the inner bearing race while installing the bearing, as it will be damaged.

Remove the wheel(s) and brake caliper(s).

The bearing cup, which normally remains in the axle housing when the axleshaft is removed, must also be replaced. Use a slide hammer-type puller to remove it from the housing.

If both bearing and seal require removal, both can be removed at the same time. Use the slide hammer in combination with a bearing removal tool (manufacturer no. T85T-1225-A or equivalent). Pivot the jaws of the tool sideways and insert behind the bearing. Let the jaws pivot out to engage the bearing and remove the bearing and seal using the slide hammer.

No, this process requires tools and techniques beyond the scope of this manual and should be left to a professional repair facility or dealer service department.

Drive out the bearing races from the wheel hub with a brass drift and install the new races with a bearing driver.

Before accessing the axleshaft, it's necessary to remove the rear wheels and then the rear brake drums or calipers and discs. These components must be removed to gain access to the axleshaft and related components within the rear axle housing.

The initial steps involve loosening the lug nuts on the rear wheels and then raising the rear of the vehicle, securely supporting it on jackstands. These steps are important to provide a stable and safe working environment for the axleshaft removal process.
