Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery if working on the power steering system.

2. Inspect and Replace Steering Components

Inspect Tie Rods and Ball Joints:
- Use a socket set to remove the wheel.
- Check the tie rods and ball joints for wear. If they are damaged, replace them.
- Torque specifications: 40-50 ft-lbs for tie rods, 70-80 ft-lbs for ball joints.
Check and Replace Power Steering Fluid:
- Locate the power steering fluid reservoir and check the fluid level. If low, top up with manufacturer-recommended fluid.
- If fluid leaks are present, replace the power steering pump or hoses as necessary.

3. Inspect and Replace CV Joints

Check CV Joints:
- Examine the CV boots for tears. If damaged, replace the CV joint assembly.
- Use a CV joint removal tool to detach the joint from the axle and replace it, ensuring proper grease is applied.

4. Inspect and Replace Suspension Components

Examine Struts and Shocks:
- Inspect for oil leakage and physical damage. If worn, replace with new struts or shocks.
- Follow the manufacturer’s torque specifications during installation.
