Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if electrical components are involved.

2. Inspect and Replace Worn Components

Sub-steps:
- Remove the rear wheel on the side where the noise is present using a socket set.
- Inspect the shock absorbers for any signs of fluid leakage.
- Check the rubber bushings for cracks or excessive wear. Replace if necessary.
- If any components are damaged or worn, remove the old part:
  - For shocks, detach the upper and lower mounting bolts, and pull the shock out.
  - For bushings, use a bushing removal tool if needed.
- Install new components by reversing the removal steps. Ensure bolts are torqued to manufacturer specifications (typically around 30-50 lb-ft for shock and bushing bolts).

3. Tighten All Fasteners

Sub-steps:
- Go through all suspension bolts and ensure they are tightened to the specified torque values.
- Use a torque wrench for accuracy.

4. Reassemble and Test

Sub-steps:
- Replace the rear wheel and lower the vehicle back to the ground.
- Reconnect the battery.
- Perform a test drive to ensure the noise has been eliminated and the vehicle handles correctly.
