Solution

1. Preparation

Gather tools and parts required for the repair.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery's negative terminal to ensure safety.

2. Inspect and Replace Power Steering Fluid

Tools Required: Fluid siphon, appropriate power steering fluid.
Remove the power steering fluid reservoir cap.
Use a fluid siphon to extract old fluid; replace with new fluid as specified by the manufacturer.
Reinstall the cap securely.

3. Inspect and Replace Faulty Components

Tools Required: Socket set, torque wrench, pry bar.
Begin by visually checking the steering rack and tie rod ends.
If damaged, remove the tie rod ends by loosening the locking nut and using a tie rod puller to detach.
Replace the tie rod ends or steering rack as necessary, ensuring to torque to manufacturer specifications (usually around 45-55 lb-ft for tie rod ends).

4. CV Joint Inspection and Replacement

Tools Required: Jack, jack stands, socket set.
Safely lift the front of the vehicle and secure it with jack stands.
Remove the wheel to access the CV joint.
Inspect the CV joint boot for tears; replace if necessary by removing the axle nut and detaching the axle from the hub.
Install a new CV joint and axle if needed, ensuring all components are torqued to specifications.

5. Reassemble and Reconnect Battery

Reinstall the wheel and lower the vehicle.
Reconnect the negative terminal of the battery.
Ensure all tools are removed from the engine bay.
