Solution

1. Preparation

Park the vehicle on a level surface and engage the parking brake.
Gather tools: socket set, jack, jack stands, and a torque wrench.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Check the fluid level; if low, top off with the recommended power steering fluid.
If the fluid is dark or contaminated, drain the old fluid from the system and replace it with new fluid.

3. Examine Steering Components

Tie Rod Ends:
- Jack up the front of the vehicle and secure it with jack stands.
- Inspect the outer and inner tie rod ends for play or damage.
- If damaged, remove the cotter pin and nut, then replace the tie rod end.
Ball Joints:
- Check ball joints for wear by trying to move them with your hands.
- If they are loose, remove the wheel and replace the ball joints as necessary.

4. Inspect Steering Rack

Look for any signs of leakage or damage in the steering rack.
If damaged, remove the steering rack from the vehicle and replace it with a new one, following the manufacturer’s specifications for installation.

5. Reassemble and Test

Reattach any components that were removed for inspection.
Ensure all bolts are tightened to the manufacturer's specified torque settings.
Reconnect the battery and lower the vehicle.
Test drive the vehicle to ensure the noise has been eliminated.
