Solution

1. Preparation

Gather tools: jack, jack stands, socket set, torque wrench, and a pry bar.
Ensure the vehicle is parked on a flat surface and the battery is disconnected for safety.

2. Inspect and Replace CV Joints

Sub-steps:
1. Raise the front of the vehicle using a jack and secure it on jack stands.
2. Remove the front wheels using a socket set.
3. Visually inspect the CV joints for cracks or tears in the rubber boots.
4. If damaged, remove the axle nut using a socket set and remove the CV joint from the transmission side.
5. Install the new CV joint by reversing the removal steps, ensuring to torque the axle nut to the manufacturer's specification (typically around 150 ft-lbs).

3. Check and Replace Suspension Components

Sub-steps:
1. Inspect the struts and shocks for leakage or damage.
2. If replacement is necessary, remove the lower and upper mounting bolts using a socket set.
3. Install new struts or shocks and torque the bolts to specifications (consult the service manual).
4. Check the sway bar links and bushings for wear; replace if necessary.

4. Verify Power Steering System

Sub-steps:
1. Check the power steering fluid level; add fluid if low.
2. If fluid is contaminated, flush the power steering system and replace it with new fluid.
3. Inspect the power steering pump for proper operation; replace if noisy or failing.
