Solution

1. Preparation

Gather tools and parts before starting the repair.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Open the hood and locate the power steering reservoir.
2. Remove the cap and check the fluid level; top off if necessary with the recommended fluid type.
3. If the fluid is dirty or contaminated, drain it and replace it with fresh fluid.

3. Inspect and Replace CV Joints

Sub-steps:
1. Safely lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the front wheels to access the CV joints.
3. Visually inspect the CV boots for tears or leaks; replace any damaged boots.
4. If the CV joints are worn, remove the axle nuts and disconnect the axles from the hub and transaxle.
5. Replace the CV joints with new ones, ensuring proper torque specifications during reassembly.

4. Inspect and Replace Wheel Bearings

Sub-steps:
1. With the wheels still off, grasp the wheel hub at the 12 and 6 o'clock positions and check for excessive play.
2. If play is detected, remove the hub assembly and inspect the wheel bearings.
3. Replace worn or damaged wheel bearings, ensuring they are properly seated and lubricated.

5. Inspect and Replace Suspension Components

Sub-steps:
1. Check control arms, bushings, and struts for visible wear or damage.
2. If any component is worn, remove it using appropriate tools and replace it.
3. Reassemble and torque all components to the manufacturer’s specifications.
