Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and securely lifted with jack stands.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Shock Absorbers

Sub-steps:
1. Remove the wheel of the affected side using a socket set.
2. Unbolt the lower and upper mounting points of the shock absorber.
3. Carefully remove the shock absorber from the mounting bracket.
4. Install the new shock absorber in reverse order, ensuring all bolts are torqued to manufacturer specifications (typically around 15-20 ft-lbs).

3. Check and Replace Sway Bar Links

Sub-steps:
1. Inspect sway bar links for wear or detachment.
2. Remove the old sway bar link by unbolting it from the sway bar and lower control arm.
3. Install the new sway bar link and tighten to manufacturer specifications.

4. Inspect Control Arms and Bushings

Sub-steps:
1. Check for any cracks or wear in the control arms and bushings.
2. If damaged, remove the control arm by unbolting it from the chassis and the ball joint.
3. Replace the control arm and reassemble, ensuring all bolts are securely torqued.
