Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and park it safely.
Disconnect the negative battery terminal to prevent any electrical issues.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; if low, top up with the manufacturer's recommended fluid.
If the fluid is dark or contaminated, drain and replace the fluid.

3. Inspect Steering Components

Lift the vehicle using a jack and secure it on jack stands.
Remove the front wheels to gain access to the suspension and steering components.
Inspect tie rods, control arms, and bushings for any signs of wear or damage. Replace any faulty components.

4. Check Wheel Bearings

Spin the wheel by hand and listen for grinding noises.
If grinding is heard, remove the wheel hub assembly and replace the bearing using a bearing puller.
Reassemble the hub and wheel, ensuring all torque specifications are met.

5. Inspect and Replace CV Joints

Remove the axle from the wheel hub by undoing the axle nut and any connecting bolts.
Inspect the CV joints for wear or damage; if damaged, replace the entire axle assembly.
Reinstall the axle, ensuring it is seated correctly in the differential.

6. Reassemble and Test

Reinstall the front wheels and lower the vehicle.
Reconnect the negative battery terminal.
Conduct a test drive to ensure the noise has been resolved.
