Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and safely lifted on jack stands.
Wear safety glasses and gloves for protection.

2. Remove Rear Wheel

Tools Required: Lug wrench, jack stands, jack
Loosen lug nuts slightly before lifting the vehicle.
Use the jack to lift the rear of the vehicle and place it on jack stands.
Remove the rear wheel by fully unscrewing the lug nuts.

3. Inspect and Replace Components

Check Shock Absorbers:
- Remove the lower mounting bolt of the shock absorber.
- Remove the upper mounting bolts from the trunk area.
- Replace with new shock absorbers if leaking or damaged.
Inspect Bushings:
- Remove any necessary components obstructing access to bushings (e.g., sway bar links).
- Check for wear and replace any damaged bushings.
Check for Loose Components:
- Tighten all suspension-related bolts to manufacturer specifications.
- Use a torque wrench to ensure proper torque settings.

4. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle from jack stands and perform a final tightening of the lug nuts in a crisscross pattern.

5. Test Drive

Conduct a test drive to ensure noises have been resolved and the vehicle rides smoothly.
