Solution

1. Preparation

Gather tools and necessary parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working with electrical components.

2. Inspect and Replace Worn CV Joints

Sub-steps:
1. Jack up the front of the vehicle and secure it with jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the CV joints for tears in the rubber boots or grease leakage.
4. If damaged, remove the axle nut and disconnect the CV joint from the hub.
5. Replace the CV joint or axle assembly as necessary.
6. Reassemble by reversing the disconnection steps and torque the axle nut to the manufacturer’s specifications (typically around 150 ft-lbs).

3. Check and Replace Suspension Components

Sub-steps:
1. Visually inspect struts and shocks for leaks or damage.
2. If struts or shocks are worn, remove the suspension components.
3. Replace with new struts/shocks, ensuring all bolts are torqued to specifications.
4. Inspect and replace any bushings that appear cracked or worn.

4. Power Steering System Check

Sub-steps:
1. Locate the power steering reservoir and check the fluid level.
2. If low, top off with the recommended power steering fluid (typically ATF or specific PS fluid).
3. Check for leaks in the power steering lines or reservoir.
4. If the fluid is contaminated, flush the system and refill.
