Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety during the repair.

2. Check and Refill Power Steering Fluid

Locate the power steering reservoir and remove the cap.
Inspect the fluid level; if low, add the recommended power steering fluid type (e.g., ATF, PS fluid).
Start the engine and turn the steering wheel from lock to lock to bleed any air from the system.

3. Inspect Suspension Components

Lift the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, bushings, and ball joints for wear or damage.
Replace any worn or damaged components as necessary, ensuring to torque bolts to manufacturer specifications (typically around 50-60 ft-lbs for control arms).

4. Inspect and Replace CV Joints (if necessary)

Remove the wheel and tire assembly to access the CV joint.
Inspect the CV boot for cracks or tears; if damaged, replace the entire CV axle.
Use a socket set to remove the axle nut, then pull the axle from the hub and replace it with the new one.

5. Check Wheel Bearings

Spin the wheel by hand to listen for any noise or grinding.
If noise is present, remove the wheel hub assembly and replace the wheel bearings.
Use a bearing press to install new bearings, ensuring proper alignment and fit.

6. Reassemble and Test

Reassemble all components in reverse order of disassembly.
Reconnect the negative battery terminal.
Perform a test drive to ensure the noise is resolved.
