Solution

1. Preparation

Gather tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and wear safety gloves.
Use a jack and jack stands to elevate the vehicle safely for inspection.

2. Inspect and Replace Worn Components

Inspect Control Arms and Bushings:
- Remove the wheel to gain access to the suspension.
- Inspect control arms for cracks and bushings for deterioration.
- If damaged, replace the control arms with new ones; torque the mounting bolts to manufacturer specifications.
Check Shock Absorbers or Struts:
- Look for oil leaks around the shock absorbers.
- If leaking or worn, remove the shock absorber by unbolting it from the top and bottom mounts.
- Install new shock absorbers, ensuring they are tightened to the correct torque.

3. Replace Sway Bar Links and Bushings

Remove Old Sway Bar Links:
- Unbolt the sway bar links from the sway bar and the lower control arm.
- Replace with new sway bar links and tighten to specifications.
Inspect Sway Bar Bushings:
- If bushings are worn, remove the sway bar and replace the bushings.
- Lubricate the new bushings and reinstall the sway bar.

4. Reassemble and Lower Vehicle

Reinstall the wheel and lower the vehicle.
Ensure all fasteners are tightened to the correct specifications.
