- If any parts are damaged, proceed to replace them.

3. Check CV Joints and Axles

Sub-steps:
- Remove the wheel from the affected side.
- Inspect the CV boots for tears and ensure the grease is intact.
- If the CV joint is damaged, replace it using the following steps:
  - Disconnect the lower control arm and the axle nut.
  - Remove the old CV joint and install the new one, ensuring it’s properly seated.

4. Inspect Wheel Bearings

Sub-steps:
- Spin the wheel by hand and listen for any grinding or roughness.
- If noise is detected, remove the hub assembly and replace the wheel bearing using a bearing press.
