Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Raise the Vehicle

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

3. Inspect and Replace Components

Inspect Struts and Shock Absorbers:
- Check for leaks and physical damage.
- If damaged, remove the struts/shock absorbers:
  - Unbolt the top mount inside the engine bay (if applicable).
  - Unscrew the bottom bolts on the strut assembly.
  - Replace with new units, torque to manufacturer specifications.
Check Control Arms and Bushings:
- Inspect control arms and bushings for wear.
- If worn, replace control arms or bushings as needed:
  - Remove the bolts securing the control arm.
  - Replace with new parts, ensuring proper alignment.
Examine Sway Bar Links:
- Check sway bar links for breakage.
- Replace if necessary by removing the bolts securing them to the sway bar and control arm.

4. Reassemble and Lower the Vehicle

Reinstall wheels and tighten lug nuts to proper torque.
Lower the vehicle back to the ground and reconnect the battery.

5. Final Inspection

Double-check all bolts and components for tightness.
Ensure that all tools are removed from the work area.
