Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Wear safety gloves and goggles during the repair.

2. Inspect and Replace Shock Absorbers

Tools Required: Socket set, torque wrench, pry bar, jack, jack stands.
Sub-steps:
1. Lift the Vehicle: Using a jack, lift the vehicle and secure it with jack stands.
2. Remove Wheel: Take off the wheel corresponding to the noise (front or rear).
3. Inspect Shock Absorbers: Look for signs of leaking fluid or physical damage.
4. Remove Old Shock Absorber:
  - Unscrew the mounting bolts at both the top and bottom of the shock absorber.
  - Use a pry bar if necessary to detach it from the mounting points.
5. Install New Shock Absorber:
  - Position the new shock absorber and secure it by tightening the mounting bolts to the manufacturer's specifications (check for torque values in the service manual).
6. Reattach Wheel: Install the wheel back and torque the lug nuts to the specified values.
7. Lower the Vehicle: Carefully remove jack stands and lower the vehicle back to the ground.

3. Inspect and Tighten Other Suspension Components

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Check Sway Bar Links: Inspect for wear and replace if necessary.
2. Tighten Loose Bolts: Go through all suspension mounting points and tighten any loose bolts to the manufacturer's torque specifications.
3. Check Control Arm Bushings: Inspect for signs of cracking or wear; replace if needed.
