Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level against the markings.
If low, add the appropriate type of power steering fluid (refer to the owner’s manual).
Replace the cap securely.

Visually inspect power steering hoses and connections for any signs of leaks or damage.
If any leaks are found, mark the affected areas for replacement.

4. Test Power Steering Pump

Reconnect the battery and start the vehicle.
With the engine running, turn the steering wheel from lock to lock; listen for unusual noises.
If noise persists or the steering remains hard, the power steering pump may need replacement.

5. Check Serpentine Belt

Inspect the serpentine belt for wear, cracks, or looseness.
If damaged, replace the belt with a new one and ensure it is properly tensioned according to specifications.

6. Replace Steering Rack (if necessary)

If the steering rack is found to be damaged, it will require replacement.
Raise the vehicle and remove the front wheels.
Disconnect the steering linkage and any mounting brackets.
Remove the old steering rack and install the new one, ensuring all connections are secure.
Torque all bolts to the manufacturer's specifications.
