Suspension and steering systems / Front suspension lower arm balljoint - renewal


Note: If the lower arm balljoint is worn, either the complete lower arm or the balljoint alone can be renewed. If the balljoint has already been renewed, it will be bolted in position; if the original balljoint is being renewed, then it will be riveted in position (see illustration).

This Section describes the renewal of a riveted balljoint.

1 Remove the front suspension lower arm as described in Section 7. It is not recommended that the balljoint be replaced with the lower arm in position on the vehicle; the accurate drilling necessary may not be possible, and the holes in the arm may be enlarged.

2 With the lower arm on the bench, use a 3 mm drill to make a pilot hole through each of the three rivets. Now use a 9 mm drill to drill the rivets to a depth of 12 mm, then use a 7 or 8 mm drift to drive the rivets out of the arm.

3 Clean any rust or dirt from the rivet holes.

4 The new balljoint is supplied with a protective plastic cover over the rubber boot and stub, and it is recommended that this remains in position until it is time to connect the balljoint to the steering knuckle.

5 Locate the new balljoint on the lower arm, and use three new bolts to secure it, inserting the bolts from the top of the arm. Tighten the nuts to the specified torque. Make sure that the location lug on the balljoint engages the hole in the lower arm (see illustration).
