Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the negative terminal of the battery to ensure safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, add the recommended power steering fluid (consult the owner’s manual for the specific type).

3. Inspect and Replace Power Steering Belt

Use a socket set to remove any covers obstructing access to the power steering belt.
Inspect the belt for fraying, cracking, or signs of wear.
If damaged, remove the belt by loosening the tensioner pulley using a wrench.
Install a new belt, ensuring it is properly aligned with all pulleys.

4. Check Power Steering Pump

Visually inspect the power steering pump for leaks or damage.
If leaking, remove the pump by disconnecting the hoses and mounting bolts.
Replace the power steering pump with a new one, ensuring all seals are intact.

5. Inspect and Replace Steering Rack (if necessary)

If the steering rack is damaged, it must be replaced.
Remove the steering column connection and any associated brackets.
Detach the steering linkage and power steering lines.
Install the new steering rack, ensuring proper alignment and torque specifications for mounting bolts.

6. Reassemble and Test

Reassemble any components removed during the repair.
Reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock to bleed the system of air.
Check for leaks and ensure the whining noise is resolved.
