Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, flashlight, tire pressure gauge, and basic hand tools.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Tire Inspection

Sub-steps:
- Remove the wheel covers or hubcaps if necessary.
- Check each tire for visible damage, such as cuts, bulges, or punctures.
- Measure tire pressure with a gauge and inflate to the manufacturer’s recommended levels.

3. Suspension Component Inspection

Sub-steps:
- Lift the vehicle using a jack and secure it with jack stands.
- Visually inspect the struts and shocks for leaks or damage.
- Check control arms and bushings for signs of wear or separation.
- If any components are worn or damaged, replace them as needed.

4. Wheel Bearing and CV Joint Check

Sub-steps:
- With the vehicle still lifted, grasp each wheel and try to rock it back and forth. Any play indicates a potential issue with the wheel bearings.
- Inspect the CV joints for torn boots or grease leakage. If found, replace the affected joint or boot.

5. Reassembly and Testing

Sub-steps:
- Reinstall the wheels and tighten lug nuts to the manufacturer’s specified torque.
- Lower the vehicle and conduct a test drive to ensure the thumping noise has been resolved.
