If any components are worn or damaged:
- Loosen the tie rod ends using a socket set.
- Replace with new tie rod ends or steering rack as necessary.
- Torque to manufacturer specifications (refer to service manual).

4. Inspect and Replace Wheel Bearings

Raise the vehicle and remove the front wheels using a socket set.
Inspect the wheel bearings for play:
- If play is detected, remove the hub assembly.
- Replace the wheel bearings using a bearing puller.
- Reassemble the hub and torque to manufacturer specifications.
