Solution

1. Preparation

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

2. Check and Refill Power Steering Fluid

Remove the power steering reservoir cap.
Inspect the fluid level; if low, refill with the manufacturer-recommended power steering fluid.
Check the fluid condition; if dark or contaminated, it may need a complete change.

3. Inspect and Replace Power Steering Hoses

Locate the power steering hoses and inspect for leaks or cracks.
If damaged, use a socket set to remove the old hoses.
Install new hoses, ensuring they are properly secured and free from kinks.

4. Test and Replace Power Steering Pump (if necessary)

If the pump is found to be faulty, locate it (usually mounted on the engine).
Remove the serpentine belt using a belt tensioner tool.
Disconnect hoses and electrical connectors from the pump.
Remove the mounting bolts and take out the pump.
Install the new pump by reversing the removal steps and refilling the system with fluid.

5. Final Assembly

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