Solution

1. Preparation

Tools Required: Jack and jack stands, torque wrench, pry bar, socket set.
Safely lift the vehicle using a jack and secure it with jack stands.
Ensure the vehicle is on a flat surface and the ignition is off.

2. Inspect Ball Joint Dust Boots

Visually check the dust boots for any cracks or tears.
If damaged, the ball joint may have been contaminated by debris and require replacement.

3. Test for Play in Ball Joint

Insert a pry bar under the lower control arm near the ball joint.
Apply upward pressure; if there is significant movement, the ball joint is likely worn and should be replaced.

4. Check for Excessive Wheel Movement

With the wheel off the ground, grasp the tire at the 12 o'clock and 6 o'clock positions and shake it.
Any noticeable play indicates worn ball joints.

5. Tighten Ball Joint Hardware

Use a torque wrench to ensure the bolts securing the ball joint are tightened to the manufacturer's specifications (consult the owner’s manual for torque values).
If the bolts are loose, retighten them according to specifications.
