Solution

1. Preparation

Gather tools and parts required for inspection and repair.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect Power Steering System

Tools Required: OBD-II scanner (if needed), fluid pump, container.
Check power steering fluid level; if low, top off with the recommended fluid type.
Look for leaks in the power steering pump or hoses.

3. Check Steering and Suspension Components

Tools Required: Socket set, torque wrench.
Lift the front of the vehicle using a jack and secure it with jack stands.
Inspect the tie rods, steering rack, and control arms for any signs of wear or damage.
Tighten any loose bolts to the manufacturer's torque specifications.

4. Inspect and Replace Wheel Bearings (if necessary)

Tools Required: Bearing puller, torque wrench, socket set.
Remove the wheel and inspect the wheel bearing for noise by spinning it by hand.
If damaged, use a bearing puller to remove the old bearing, then install a new one and torque to specifications.

5. Check and Replace CV Joints (if necessary)
