Preparations

Cleaning around the ball joint







- Blow clean around the ball joint with compressed air.
- Generously spray the ball joint and the screw and nut retaining the ball joint using rust penetrator.

Removing the ball joint from the wheel spindle







NOTE: Do not insert a screwdriver or punch between the ears on the wheel spindle.

- If the screw has rusted solid, slacken off the nut a few turns. Knock the screw so that it loosens.
- Remove the screw and the nut.
- Spray the ball joint with rust penetrator again.







NOTE: The inner diameter of the socket must be larger than the outer diameter of the cover. This is to prevent damage to the cover.

- Tap the ball joint off the wheel spindle.
- Use a socket as a spacer.
- Spray the ball joint with rust penetrator again.







- Move the ball joint up and down by hand (or a jimmy bar can be used) until the ball joint detaches from the wheel spindle.
- Withdraw the drive shaft from the hub.
- Twist the spring strut to one side. Hang the drive shaft so that the control arm is not in contact with the drive shafts.
