Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick.
If low, add the appropriate type of power steering fluid as specified in the owner's manual.
Replace the cap securely.

3. Check for Leaks

Visually inspect all hoses, the power steering pump, and the steering rack for signs of fluid leaks.
If leaks are found, identify the source and replace damaged hoses or components.

4. Test the Power Steering Pump

Start the engine and turn the steering wheel from lock to lock while observing the power steering pump for noise.
If the pump continues to whine, it may need to be replaced.
If the noise ceases with fluid added, monitor for leaks or check for air in the system.

5. Replace Power Steering Pump (if necessary)

Disconnect the power steering fluid lines from the pump.
Remove the mounting bolts and lift the pump out.
Install the new pump, securing it with mounting bolts to the specified torque.
Reconnect the fluid lines and check for tightness.

6. Bleed the Power Steering System

Fill the reservoir with the appropriate power steering fluid.
Start the engine and turn the steering wheel from lock to lock to purge air.
Check the fluid level and add more fluid as needed.
