Solution

1. Preparation

Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, lubricant (silicone spray or grease).
Safely lift the vehicle using a jack and secure it with jack stands.

2. Inspect Suspension Components

Sub-steps:
- Remove the front or rear wheels (depending on the affected area).
- Visually inspect the shock absorbers for leaks or damage.
- Check for wear on bushings, look for cracks or splits.
- Use a pry bar to check for play in the ball joints and other pivot points.

3. Replace Worn Components

Sub-steps:
- If any bushings are worn, remove the old bushings using a socket set and replace them with new ones, ensuring proper alignment.
- If strut mounts or shock absorbers are damaged, remove the strut assembly using a socket set, replace the components, and reassemble.
- Torque all bolts and nuts to manufacturer specifications.

4. Lubricate Moving Parts

Sub-steps:
- Apply silicone spray or grease to all moving parts such as bushings or joints to reduce friction and noise.
- Ensure excess lubricant does not contact the brake components.

5. Reassemble and Test

Sub-steps:
- Reinstall wheels and lower the vehicle.
- Conduct a test drive to check for noise elimination and ensure proper handling.
