Solution

1. Preparation

Tools Required: Socket set, screwdrivers, power steering fluid, OBD-II scanner.
Ensure the vehicle is on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; it should be within the "MIN" and "MAX" marks.
If low, add the recommended type of power steering fluid (check owner's manual for specifications).
Recheck for leaks or any signs of contamination in the fluid.

3. Check for Leaks

Visually inspect all power steering lines, hoses, and connections for signs of fluid leaks.
Tighten any loose connections and replace any damaged hoses.
If leaks are found, replace the affected components as needed.

4. Inspect Power Steering Pump

Locate the power steering pump and check for signs of wear or leakage.
With the engine running, listen for whining or grinding sounds from the pump.
If the pump is faulty, disconnect the inlet and outlet hoses and remove the pump using the socket set.
Install the new pump, ensuring all connections are tight.

5. Test Steering Rack and Pinion

Check the steering rack for any visible damage or excessive play.
If necessary, remove the steering rack by disconnecting it from the steering column and suspension components.
Inspect the inner and outer tie rods for wear; replace if needed.

6. Reassemble and Reconnect Battery

Reconnect the negative battery terminal.
Start the engine and turn the steering wheel from lock to lock several times to bleed the system.
Check the fluid level again and add more if necessary.
