Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Worn Components

Inspect Suspension:
- Remove the wheel to access the suspension components.
- Check the upper and lower control arms, bushings, and ball joints for wear.
Replace Worn Parts:
- If any bushings or joints are damaged, remove the old parts using a socket set and replace them with new components. Ensure they are properly lubricated if required.
- Torque all bolts to manufacturer specifications.

3. Check Shock Absorbers/Struts

Remove and Inspect:
- Remove the shock absorber or strut assembly from the vehicle.
- Inspect for signs of leakage or physical damage.
Replace if Necessary:
- If the shock absorber is found to be faulty, replace it with a new unit. Reinstall and torque to specifications.

4. Reassemble and Test

Reattach the wheel and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
Test drive the vehicle over bumps to verify the noise has been resolved.
