Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Disconnect the battery to ensure safety when working on electronic components.

2. Inspect Steering Components

Tools Required: Socket set, torque wrench, pry bar
Remove the front wheels to access the steering and suspension components.
Inspect the tie rods and ball joints for any play or damage. If worn, replace them:
- Use a socket set to remove the nuts securing the tie rods/ball joints.
- Replace with new parts and torque to manufacturer specifications.

3. Check Power Steering System

Tools Required: OBD-II scanner, fluid container
Locate the power steering reservoir and check fluid level. If low, top it off with the recommended fluid.
If the fluid is contaminated, it may require a flush:
- Disconnect the return line from the reservoir.
- Use a fluid container to catch old fluid while cycling the steering wheel to remove old fluid.
- Reconnect the line and refill with new power steering fluid.

4. Inspect Wheel Bearings

Tools Required: Bearing puller, torque wrench
Check for play in the wheel bearings by gripping the tire at the 12 and 6 o'clock positions and rocking it.
If there is play, remove the wheel and hub assembly:
- Use a bearing puller to extract the old bearing.
- Install the new bearing and torque to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheels and torque the lug nuts to specifications.
Reconnect the battery.
Perform a test drive to ensure the grinding noise has been resolved.
