Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, screwdriver, pry bar, and a stethoscope (or similar tool for noise detection).
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and check fluid level.
2. If low, top off with the manufacturer-recommended power steering fluid.
3. If fluid is dirty or burnt, drain and replace with new fluid.

3. Examine Suspension and Steering Components

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it with jack stands.
2. Inspect control arms, tie rods, and strut mounts for wear or damage.
3. Use a pry bar to check for play in the ball joints and tie rod ends.
4. Replace any worn or damaged components as necessary.

4. Check Wheel Bearings and CV Joints

Sub-steps:
1. Spin the front wheels by hand and listen for any grinding noise indicating bearing failure.
2. Inspect CV joint boots for cracks or tears; replace if necessary.
3. If bearings are worn, remove the hub assembly and replace the bearings.

5. Reassemble and Torque Components

Sub-steps:
1. Reinstall any components that were removed during inspection.
2. Use a torque wrench to tighten all fasteners to the manufacturer-specified torque values.
