Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Check Power Steering Fluid

Tools Required: Rags, funnel.
Check the power steering fluid reservoir for proper fluid level.
If low, top off with the manufacturer-recommended fluid type.
Inspect for leaks around the reservoir and hoses.

Raise the front of the vehicle and secure it on jack stands.
Remove the front wheels to access the CV joints.
Inspect the CV boots for tears or damage; replace if necessary.
Check the joints for play or grinding; replace if worn.

4. Examine Wheel Bearings

Tools Required: Bearing puller, socket set.
Spin the wheel hub while the vehicle is elevated to listen for noise.
If noise is present, remove the hub assembly and inspect the bearings.
Replace any worn or damaged bearings, ensuring proper torque specs upon reassembly.
