Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Control Arm Bushings

Tools Required: Socket set, torque wrench, pry bar, ball joint separator.
Raise the front of the vehicle and secure it on jack stands.
Remove the wheel to access the control arm.
Use a pry bar to check for play in the control arm bushings.
If damaged, remove the control arm by unbolting it from the chassis and the ball joint.
Replace the bushings with new ones, ensuring they are properly seated.
Reinstall the control arm and torque bolts to manufacturer specifications.

3. Replace Ball Joints

Tools Required: Ball joint separator, socket set, torque wrench.
If play is detected in the ball joints, use a ball joint separator to remove the old joint.
Install the new ball joint and secure it using the proper torque specifications.

4. Inspect and Replace Sway Bar Links

Tools Required: Socket set, torque wrench.
Check the sway bar links for any signs of damage or wear.
If faulty, remove the sway bar link from the sway bar and lower control arm.
Install new sway bar links and torque them to specifications.

5. Check Struts and Shocks
