Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Use wheel chocks to prevent movement.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is originating.
Secure the vehicle with jack stands for safety.

3. Inspect Suspension Components

Shock Absorbers/Struts:
- Remove the protective dust covers if applicable.
- Check for any fluid leakage on the shock absorber body.
- Press down on the suspension to see if it rebounds excessively.
Sway Bar Links:
- Inspect sway bar links for any signs of wear or looseness.
- Use a wrench to tighten if necessary, or replace if damaged.
Control Arm Bushings:
- Check the control arm bushings for cracks or signs of wear.
- Replace bushings if they appear damaged.

4. Replace Components (if necessary)

If any components are determined to be worn or damaged, proceed to replace them:
- Shock Absorbers/Struts:
  - Remove the mounting bolts and detach the unit.
  - Install the new shock absorber or strut, ensuring it is aligned properly.
  - Torque the mounting bolts to the manufacturer's specifications.
- Sway Bar Links:
  - Remove the old sway bar link by loosening the bolts.
  - Install the new sway bar link and torque to specifications.
- Control Arm Bushings:
  - Remove the control arm from the vehicle, if needed.
  - Press out the old bushings and press in new ones.
  - Reinstall the control arm and torque bolts to specifications.

5. Lower the Vehicle

Carefully remove jack stands and lower the vehicle back to the ground.
