Solution

1. Preparation

Gather tools and park the vehicle on a level surface.
Ensure the vehicle is in park and the engine is off.
Raise the front of the vehicle using a jack and secure it with jack stands.

2. Inspect Steering and Suspension Components

Sub-steps:
- Visually inspect the tie rods, ball joints, and control arms for any signs of wear or damage.
- Check the CV joints for any torn boots or grease leakage.
- Use a wrench to check the tightness of all relevant bolts.

3. Address Power Steering Issues

Sub-steps:
- If the power steering fluid is low, top it off with the recommended fluid type (check the owner's manual).
- If the fluid is discolored or contains debris, a fluid flush may be necessary.

4. Replace Worn Components

Sub-steps:
- If any components are found to be damaged during inspection, replace them according to manufacturer specifications.
- For CV joint replacement, remove the wheel, brake caliper, and rotor, then disconnect the axle from the hub.

5. Reassemble and Lower Vehicle

Sub-steps:
- Reinstall any removed components in reverse order, ensuring all bolts are torqued to specification.
- Lower the vehicle and test the steering functionality before taking it for a drive.
