Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery if necessary for safety.

2. Inspect Power Steering System

Check the power steering fluid reservoir for proper level.
If low, add the recommended fluid type (typically ATF or a specific power steering fluid).
Look for leaks in hoses and connections; replace any damaged hoses.

3. Examine CV Joints

Raise the front of the vehicle using a jack and secure it with jack stands.
Inspect the CV joints for tears or damage in the rubber boots.
If damaged, replace the CV joint or axle assembly. Use a socket set to remove the axle nut and disconnect the joint from the hub.

4. Check Wheel Bearings

Spin each front wheel by hand to listen for noise or roughness.
If noise is detected, remove the wheel and inspect the bearing.
If necessary, replace the wheel bearing by removing the hub assembly and pressing out the old bearing.

5. Inspect Suspension Components

Check control arms, struts, and bushings for wear.
Replace any worn components, using a torque wrench to ensure proper torque specifications during reassembly.
