Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir and remove the cap.
If fluid is low or dirty, drain the existing fluid using a turkey baster.
Refill with the manufacturer-recommended power steering fluid.

3. Inspect and Replace CV Joints

Lift the front of the vehicle using a jack and secure with jack stands.
Remove the wheel to access the CV joint.
Inspect the CV boot for tears; replace if necessary.
If the CV joint is damaged, remove the axle nut and disconnect the joint from the transmission.
Install the new CV joint, ensuring proper torque specifications are followed (typically 150-200 ft-lbs for axle nut).

4. Check and Replace Wheel Bearings

With the wheel removed, grasp the hub and check for play by rocking it back and forth.
If play is detected, remove the hub assembly.
Replace the wheel bearing by pressing it out and installing a new bearing using a bearing press.
Reassemble the hub and wheel, following manufacturer torque specifications.

5. Inspect and Repair Suspension Components

Check all suspension components including control arms, struts, and bushings for wear or damage.
Replace any worn or damaged components using appropriate tools and techniques.
Align the suspension as needed after replacing components.
