Solution

1. Preparation

Gather necessary tools and parts.
Park the car on a flat surface and engage the parking brake.
Disconnect the 12V battery for safety.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
If applicable, remove the reservoir cap and check the fluid level; top off with manufacturer's recommended fluid if low.

3. Inspect Steering Components

Raise the front of the vehicle using a jack and secure with jack stands.
Remove the front wheels for better access.
Inspect tie rods, control arms, and bushings for any cracks or excessive wear.

4. Test Electric Power Steering

Reconnect the battery and power on the vehicle.
Turn the steering wheel from lock to lock while stationary; listen for any abnormal noises.
If the noise persists, consider replacing the power steering motor or associated wiring.

5. Wheel Bearing Inspection

Rotate each wheel by hand to check for smoothness; listen for grinding noises.
If a bearing is found to be faulty, remove the affected wheel and hub assembly.
Replace the wheel bearing using a bearing puller and install a new bearing with the proper torque specifications.

6. Tire Inspection and Alignment

Check tire pressure and adjust to the recommended levels.
Inspect for uneven wear patterns that may indicate misalignment.
If necessary, perform a wheel alignment following the manufacturer’s specifications.
