Solution

1. Preparation

Gather tools such as a jack, jack stands, wrench set, and a mechanic's stethoscope.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use a jack to lift the vehicle and securely place it on jack stands.
Ensure all safety precautions are followed to prevent accidents.

3. Inspect Suspension Components

Check the following components for wear or damage:
- Shock absorbers/struts: Look for leaks or signs of wear.
- Control arms: Inspect for bending or cracking.
- Ball joints: Check for play or excessive wear.
- Sway bar links: Ensure they are not loose or damaged.
Replace any damaged components as needed.

4. Replace Worn Bushings and Mounts

If any bushings or mounts are found to be worn, follow these steps:
- Remove the affected suspension component (e.g., control arm).
- Press out the old bushing using a bushing removal tool.
- Install the new bushing, ensuring it is properly aligned and seated.
- Reinstall the suspension component and torque bolts to manufacturer specifications.

5. Reassemble and Lower Vehicle

After repairs, reassemble all components and ensure all fasteners are tightened.
Carefully lower the vehicle back to the ground using the jack.
