Toyota RAV4 Service Manual: Rear axle hub and bearing

Components

On-vehicle inspection

1. Remove rear wheel

2. Disconnect rear drive shaft assembly lh (for 4wd)

1. Disconnect the drive shaft (see page ds-69).

3. Remove rear disc brake cylinder assembly lh (see page br-55)

4. Remove rear disc (see page br-57)

5. Check bearing backlash and axle hub deviation

1. Using a dial indicator, measure the backlash near the center of the axle hub.

Maximum backlash: 0.05 Mm (0.0020 In.)

If the backlash is greater than the maximum, replace the axle hub.

2. Using a dial indicator, measure the disc runout 10 mm (0.39 In.) Inside the outer edge of the disc.

Maximum deviation: 0.08 Mm (0.0031 In.) For 2wd

0.06 Mm (0.0024 In.) For 4wd

Notice:

If the runout exceeds the maximum, change the installation positions of the rear disc and axle hub so that the runout will be as low as possible. If the runout exceeds the maximum even when the installation positions are changed, shave the rear disc. If the rear disc needs to be shaved to less than the minimum, replace the rear disc. If the rear disc is replaced, perform the runout inspection again. If the runout still exceeds the maximum, replace the hub and bearing with a new one.
