Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Lift the vehicle using a hydraulic jack and secure it on jack stands.

2. Inspect Suspension Components

Sub-steps:
- Remove the front or rear wheels (depending on where the noise is coming from) using a lug wrench.
- Visually inspect the shock absorbers for leaks or physical damage.
- Check the control arms, bushings, and ball joints for wear and movement.

3. Tighten Loose Bolts

Sub-steps:
- Using a torque wrench, check and tighten all suspension-related bolts to the manufacturer’s specifications.
- Focus on the strut mounts, sway bar links, and control arm connections.

4. Replace Worn Components

Sub-steps:
- If any components are found to be damaged (e.g., sway bar links, bushings, or struts), remove the defective part.
- Install new parts, ensuring all fasteners are torqued to specification.
- Reassemble any components removed during inspection.

5. Reassembly and Lower Vehicle

Sub-steps:
- Reinstall the wheels and hand-tighten the lug nuts.
- Lower the vehicle from the jack stands.
- Torque the lug nuts to the appropriate specification.
