Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any accidental shorts.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add the appropriate type of power steering fluid if low.
Start the engine and turn the steering wheel from lock to lock to circulate fluid. Check for improvement in noise.

3. Inspect and Replace Component

If the issue persists:

Wheel Bearings:
- Lift the vehicle using a jack and secure it on jack stands.
- Remove the wheel to gain access to the wheel bearing.
- Check for play by wiggling the wheel; if it feels loose, remove the hub assembly and replace the bearing.
- Torque the new bearing to manufacturer specifications during installation.
CV Joints:
- Inspect the CV boots for cracks or tears.
- If damaged, remove the axle assembly from the transmission and replace the CV joint or entire axle.
- Reinstall and torque bolts to the recommended specifications.

4. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Start the vehicle and take a test drive to confirm the noise is resolved.
