Solution

1. Preparation

Tools Required: Socket set, torque wrench, pry bar, jack stands, safety glasses.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the noise is coming from.
Secure the vehicle with jack stands to ensure safety while working underneath.

3. Inspect Suspension Components

Sub-steps:
- Visually check the condition of the shock absorbers for leaks or damage.
- Inspect control arms, sway bar links, and bushings for cracks or excessive wear.
- Ensure all mounting bolts are tightened to the manufacturer’s specifications.

4. Replace Worn or Damaged Components

Sub-steps:
- If any component is found to be damaged or excessively worn, remove the corresponding parts.
- For example, if replacing a shock absorber:
  - Remove the lower and upper mounting bolts using a socket.
  - Carefully remove the old shock and install the new one in reverse order.
  - Torque the bolts to manufacturer specifications (check service manual for exact torque values).
- Repeat for any other components that show signs of wear.

5. Reassemble and Lower Vehicle

After replacing the damaged parts, double-check that all components are securely fastened.
Remove jack stands and lower the vehicle back to the ground.
