Fig. 5 Checking lower ball joint for wear
Lower ball joints are a loose fit when not connected to the steering knuckle. Wear may be checked without disassembling the ball stud as follows:
1. Support weight of control arms at wheel hub and drum.
2. Measure distance between tip of ball stud and tip of grease fitting below ball joint, Fig. 5.
3. Move support to control arm to allow wheel hub and drum to hang free. Measure distance as in Step 2. If difference in measurements exceeds 3/32
inch, ball joint is worn and should be replaced.
