Lift the front of the vehicle securely using a jack and support it with jack stands.
Remove the wheel to access the hub assembly.
Grasp the hub and check for any excessive play; if present, remove the hub assembly.
Replace the wheel bearing if it is worn or damaged, using a bearing press if necessary.

4. Inspect Steering Linkage and Suspension

Examine tie rods, control arms, and bushings for signs of wear or damage.
Replace any worn components, ensuring to torque bolts to the manufacturer's specifications.

5. Inspect Brakes

Remove the wheel and inspect brake pads and rotors for wear.
Clean any debris from the brakes and replace pads or rotors if they are worn down.
