Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Raise the Vehicle

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

3. Inspect and Replace Components

Shocks/Struts:
- Remove the mounting bolts for the shock absorbers.
- Replace with new shocks/struts if they are leaking or show signs of wear.
- Torque bolts to manufacturer specifications (typically around 15-20 ft-lbs).
Bushings:
- Check control arm and sway bar bushings for deterioration and replace if necessary.
- Remove old bushings using a bushing removal tool, and install new ones ensuring proper alignment.
Sway Bar Links:
- If sway bar links are damaged, remove them by unscrewing the bolts.
- Install new sway bar links and tighten to the specified torque (usually 30-35 ft-lbs).

4. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle from the jack stands.
Recheck all fasteners and ensure they are tightened properly.
