Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir (typically near the engine).
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, use the appropriate power steering fluid specified in the owner's manual to refill.

3. Inspect and Replace Power Steering Pump (if necessary)

Tools Required: Socket set, wrench set, power steering fluid
Disconnect the negative battery terminal to prevent electrical shorts.
Remove any components obstructing access to the power steering pump.
Disconnect the power steering hoses from the pump, being cautious of fluid spillage.
Unbolt the pump from its mounting bracket and remove it.
Install the new power steering pump by reversing the removal steps. Ensure all connections are tight.

4. Check and Replace Steering Rack (if necessary)

Tools Required: Torque wrench, socket set
If noise persists after pump replacement, inspect the steering rack.
Remove the steering column covers, and disconnect the steering linkage.
Unbolt the steering rack from the subframe and remove it from the vehicle.
Install the new steering rack by reversing the removal steps and torque the bolts to manufacturer specifications.

5. Final Steps

Reconnect the battery terminal.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check the fluid level again and top off if needed.
