Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the dipstick or markings on the reservoir.
If low, top off with the manufacturer-recommended power steering fluid.
Check for any visible leaks around hoses and connections.

3. Inspect Power Steering Pump

Remove any covers or components obstructing access to the power steering pump.
Visually inspect the pump for leaks or damage.
If necessary, disconnect the power steering pump by removing bolts and hoses carefully.
Replace the power steering pump if it shows signs of failure (e.g., noise, leaks).

4. Examine Steering Rack

Inspect the steering rack for any visible leaks or damage.
If there are leaks, the steering rack may need to be replaced.
Remove the steering rack by disconnecting the tie rod ends and any connecting bolts.

5. Reconnect and Test

Reconnect the battery and ensure all components are securely in place.
Start the engine and check for any leaks or abnormal noises.
Test drive the vehicle to verify that the steering assist is functioning correctly and that the steering light is off.
