2. Inspect Steering Components

Check Tie Rod Ends:
- Jack up the front of the vehicle and secure it on jack stands.
- Visually inspect the tie rod ends for excessive play or damage.
- Use a pry bar to check for movement; replace if worn.
Examine Ball Joints:
- Inspect the ball joints for wear or play by wiggling the wheel while it’s off the ground.
- If damaged, replace the ball joints.

3. Check Power Steering System

Fluid Level:
- Locate the power steering reservoir and check fluid level; top off if low.
Inspect for Leaks:

- Replace any damaged hoses or seals.

4. Inspect Steering Rack

Check for Play:
- With the vehicle still elevated, have someone turn the steering wheel while you observe the steering rack.
- If excessive movement is observed, the steering rack may need replacement.
