- Use a jack to lift the front of the vehicle and secure with jack stands.
Inspect Tie Rods and Ball Joints:
- Visually examine tie rods and ball joints for any play or damage.
- Use a pry bar to check for excessive movement in these components.
Tighten Loose Components:
- If any components appear loose, tighten them to the manufacturer's torque specifications.

4. Check Wheel Bearings

Inspect Bearings:
- Spin each front wheel and listen for abnormal noises.
- If noise is detected, remove the wheel and inspect the bearings for wear.
Replace Bearings if Necessary:
- If bearings are worn, remove the hub assembly, replace bearings, and reassemble.

5. Reassemble and Test Drive
