Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety goggles and gloves.

2. Raise the Vehicle

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

3. Inspect and Tighten Suspension Components

Check the strut assembly for signs of wear or leaks.
Inspect control arms, bushings, and sway bar links for damage.
Tighten any loose bolts or nuts to manufacturer specifications (consult the service manual for torque values).

4. Replace Worn Components

If any parts are damaged (e.g., bushings, strut mounts), remove them:
- Use a socket set to unbolt the components.
- Replace them with new, OEM or equivalent parts.
- Reinstall and torque to specifications.

5. Reassemble and Lower the Vehicle

Reinstall the wheels and lower the vehicle from the jack stands.
Perform a final check to ensure all fasteners are tight and components are properly aligned.
