Was told I needed to replace rear axle and drive shaft because you can’t just replace the bearings in this model vehicle. It has a shake in the rear at low speed between 20 and 45 mph.

Welcome to 2CarPros.

The axle shaft which has the CV joints on it is separate from the hub bearing. I wonder if the terminology is getting mixed up. If the bearing is bad, it can be replaced. If the axle shaft is bad, it can be replaced, and I'm not sure why they said the drive shaft needs replaced other than they may be referring to the axle as the drive shaft. So, that will need confirmed.

Here are the directions for replacement. The attached pictures correlate with these directions.

REAR AXLE HUB AND BEARING

Components

ON-VEHICLE INSPECTION

1. INSPECT REAR AXLE HUB BEARING LOOSENESS
a. Using a dial indicator, check for looseness near the center of the axle hub.
Maximum: 0 mm (0 inch)
If looseness exceeds the maximum, replace the axle hub assembly.

NOTICE: Ensure that the dial indicator is set at right angles to the measurement surface.

2. INSPECT REAR AXLE HUB BEARING RUNOUT
a. Using a dial indicator, check for runout in the surface of the axle hub outside the hub bolt.
Maximum: 0.08 mm (0.0031 inch)
If runout exceeds the maximum, replace the axle hub assembly.

NOTICE: 30 Ensure that the dial indicator is set at right angles to the measurement surface.

__________________________________

If you look at picture 1, it is an exploded view of the components. It shows the axle hub assembly and the axle. They are separate components. If you look at the last two pictures, I copied the specific parts. The first is the hub bearing and the second shows the axle with CV joints.

Let let me know if this helps or if you have other questions.

Take care,
Joe
