AXLE SHAFT
Note: The oil level in the housing is close to the bottom of the axle flange. To minimize oil spills, raise the side
of the vehicle high enough so that the oil level is below the bottom of the axle flange. If both axles have
to be removed at the same time then all oil should be drained from the housing to minimize oil spills.
Note: This procedure does not require removing the drive axle assembly from the vehicle.
This section is one section of a complete service
manual. Before starting any procedure, read all
warnings and instructions that are located in the
Service Guidelines chapter.
WARNING
Bearings may be frozen on the shaft and may explode
into small fragments while being pressed off of the
shaft.
The entire bearing should be enclosed in a steel
housing while being pressed off of the axle.
Failure to enclose the bearing may result in severe
personal injury.

Replace Axle Bearing
Note: A 10-ton press is required to replace the axle
bearing.
Note: The axle bearing will be damaged when it is
removed.
1: Remove the axle from the vehicle.
2: Place the axle in a press and install a steel guard
to fully enclose the bearing.
3: Press the bearing off of the axle, discard the
bearing retainer.
4: Clean and lightly lubricate the axle shaft.
Note: If your bearing has an external O-ring around
the axle bearing make sure that the bearing
is orientated so that the O-ring is farthest
away from the axle hub. See the illustration
to the left.
5: Install a new bearing and bearing retainer and
press into place.
Do not reuse the axle bearing retainer. The retainer
is damaged on removal and must be replaced.
Reusing an old retainer may result in the bearing
coming off of the axle causing an accident with severe
personal injury and/or property damage.
