Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, add the appropriate power steering fluid as specified in the owner's manual.
Replace the cap securely.

3. Inspect Steering System Components

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack for any signs of leaks or damage.
Check the condition of the tie rod ends and ball joints for wear or play.
Move the steering wheel side to side and observe the components for any unusual movement.

4. Test Power Steering Pump

Start the engine and turn the steering wheel from lock to lock while listening for any abnormal sounds from the power steering pump.
If noise persists, remove the power steering pump for inspection.
Replace if there are signs of wear or if it fails to operate smoothly.

5. Reassemble and Lower Vehicle

If any components were removed, reassemble them in the reverse order of disassembly.
Lower the vehicle back to the ground.
Reconnect the negative battery terminal.
