Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, power steering fluid, and safety gloves.
Elevate the vehicle and secure it with jack stands. Remove the front wheels for better access to components.

2. Inspect Power Steering System

Sub-steps:
1. Check the power steering fluid reservoir and add fluid if low.
2. If fluid is contaminated (dark or gritty), drain and replace with manufacturer-recommended fluid.
3. Inspect hoses for leaks or cracks and replace as necessary.

3. Examine CV Joints and Boots

Sub-steps:
1. Inspect the outer CV boots for tears or grease leakage.
2. If a boot is damaged, remove the axle (may require socket set).
3. Replace the CV joint if it shows signs of wear or grinding.

4. Check Wheel Bearings

Sub-steps:
1. With the wheel removed, grasp the wheel hub and check for play by rocking it in and out.
2. If play is detected, remove the hub and inspect the bearing.
3. Replace the wheel bearing if it shows signs of wear or if it is grinding.

5. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, bushings, and ball joints for signs of wear or damage.
2. Replace any worn or damaged suspension components.
3. Reassemble all components and ensure all bolts are torqued to manufacturer specifications.
