Solution

1. Preparation

Gather tools and parts needed for inspection and repairs.
Tools Required: Jack and jack stands, socket set, torque wrench, pry bar, wheel chocks.
Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Inspect Power Steering System

Sub-steps:
1. Open the hood and locate the power steering fluid reservoir.
2. Check the fluid level; if low, top it off with the manufacturer-recommended fluid.
3. Inspect the fluid for contaminants; if dirty, consider a fluid flush.

3. Examine CV Joints

Sub-steps:
1. Lift the front of the vehicle and secure it with jack stands.
2. Rotate the front wheels by hand; listen for grinding noises.
3. Inspect the CV boots for tears or leaks; replace if damaged.
4. If necessary, replace the CV joints by removing the axle nut and disconnecting the axle from the transmission.

4. Check Wheel Bearings

Sub-steps:
1. With the vehicle lifted, shake each wheel to check for play.
2. If play is detected, remove the wheel and inspect the bearing assembly.
3. Replace any worn or damaged bearings using a bearing puller and press.

5. Inspect Suspension Components

Sub-steps:
1. Visually inspect control arms, struts, and bushings for signs of wear or damage.
2. Use a pry bar to check for excessive movement in bushings.
3. Replace any worn components as needed, ensuring to torque bolts to manufacturer specifications.
