Solution

1. Preparation

Gather tools and parts needed for inspection and repair.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Replace Steering Components

Inspect Power Steering Fluid:
- Remove the power steering reservoir cap and check fluid level. If low, top up with the appropriate fluid type as specified in the owner's manual.
Check Steering Components:
- Lift the front of the vehicle with a jack and secure with jack stands.
- Visually inspect the tie rods, ball joints, and rack and pinion for wear or damage.
- If any components are damaged, proceed to replace them:
  - Remove the wheel to gain access to the steering components.
  - Use a socket set to unbolt the affected parts, replacing them with new components.
  - Torque bolts to manufacturer specifications.

3. Inspect and Replace Wheel Bearings

Check Wheel Bearings:
- Spin each wheel by hand to listen for any grinding noise.
- If noise is present, remove the wheel and brake assembly to access the bearings.
- Replace any worn or damaged bearings using a bearing puller and press.
- Ensure bearings are properly lubricated and installed.

4. Inspect Tires

Tire Inspection:
- Check each tire for irregular wear patterns and ensure they are properly inflated.
- Rotate or replace tires if necessary, following the manufacturer's recommendations for rotation patterns.
