Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Check and Top Off 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 specifications).

3. Inspect Power Steering Pump

Remove any components obstructing access to the power steering pump.
Visually inspect the pump for leaks or damage.
If noise persists even with adequate fluid, consider replacing the pump.
To remove the pump, disconnect the inlet and outlet hoses and unbolt the pump from its mounting.

4. Check Steering Rack

Inspect the steering rack for any signs of fluid leaks or damage.
If the rack is leaking or damaged, it may need to be replaced.
To replace the steering rack, disconnect the steering column from the rack and remove the mounting bolts.
Install the new rack by reversing the removal steps, ensuring all connections are secure and torqued to specifications.

5. Final Assembly and Testing

Reconnect any components removed during the repair.
Refill the power steering fluid reservoir to the proper level.
Reconnect the battery and start the vehicle.
Turn the steering wheel from lock to lock to bleed air from the system.
