Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Safety: Engage the parking brake and wear safety glasses.

2. Raise the Vehicle

Use a jack to lift the vehicle and secure it on jack stands.
Remove the wheels for better access to suspension components.

3. Inspect and Replace Components

Shock Absorbers/Struts:
- Inspect for leaks; if leaking, remove the old shock/strut using a socket set.
- Replace with new shock absorbers, ensuring proper alignment.
- Torque bolts to manufacturer's specifications (typically around 30-50 lb-ft).
Sway Bar Links:
- Inspect sway bar links for wear; if damaged, use a wrench to remove.
- Install new links, ensuring they are tight and torqued to specifications.
Bushings:
- Check control arm bushings for wear; replace if cracked or deteriorated.
- Use a bushing removal tool if necessary, and install new bushings using a press.

4. Reassemble and Lower Vehicle

Reattach wheels and hand-tighten lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque lug nuts to specifications (typically around 100-150 lb-ft).

5. Final Inspection

Perform a final visual inspection of all replaced components.
Check for any loose parts before taking the vehicle for a test drive.
