Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Lift the vehicle using a hydraulic jack and secure it with jack stands.

2. Inspect and Remove Affected Components

Sub-steps:
- Remove the front or rear wheel, depending on where the noise originates (use a lug wrench).
- Inspect the strut assembly, control arms, and bushings for visible damage.
- If any component is identified as faulty, proceed to remove it by loosening the bolts with a socket set.

3. Replace Damaged Components

Sub-steps:
- Replace worn or damaged bushings or mounts with new parts.
- If struts are worn, remove them by unscrewing the bolts at the top mount and lower control arm.
- Install the new struts or components, ensuring they are properly seated and aligned.
- Torque the bolts to the manufacturer’s specifications.

4. Reassemble and Recheck

Sub-steps:
- Reinstall the wheel and tighten lug nuts to the specified torque.
