Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check fluid levels; top up with the recommended fluid type if low.
If the fluid is contaminated, drain the old fluid using a siphon pump and refill with new fluid.

3. Replace Worn Suspension Components

Remove Wheels:
- Use a jack to lift the vehicle and secure it on jack stands.
- Remove the lug nuts using a socket set and take off the wheels.
Inspect Components:
- Check control arms, bushings, and struts for wear and replace as necessary.
Install New Components:
- If any components are worn, remove the old parts by unscrewing bolts and installing new ones using a torque wrench to the manufacturer’s specified torque settings.

4. Inspect and Replace CV Joints if Necessary

Remove Axles:
- If CV joints are damaged, remove the axle nut using a socket set and extract the axle from the hub.
Replace CV Joint:
- Remove the damaged CV joint and install a new one, ensuring proper alignment and securing with the appropriate fasteners.

5. Reassemble Vehicle

Reinstall the wheels and lower the vehicle.
Tighten lug nuts in a crisscross pattern to the specified torque.
