Solution

1. Preparation

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

2. Check 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 recommended type of power steering fluid (usually ATF or specific PS fluid) until the correct level is reached.
Reinstall the cap securely.

3. Inspect and Replace Power Steering Hoses

Visually inspect all power steering hoses for cracks, fraying, or leaks.
If damaged, use a socket set to remove the old hoses.
Install new hoses, ensuring that all connections are tight and secure.
Use hose clamps as necessary and check for leaks after installation.

4. Test Power Steering Pump

Locate the power steering pump, typically mounted on the front of the engine.
Inspect visually for any signs of damage or leaks.
If the pump is noisy or not functioning, it may need replacement.
To replace, remove the drive belt (using a belt tensioner tool), disconnect fluid lines, and unbolt the pump.
Install the new pump, reconnect all lines, and replace the drive belt, ensuring proper tension.

5. Bleed the Power Steering System

With the engine running, turn the steering wheel fully left and right several times to bleed air from the system.
Check fluid levels again and top off if necessary.
Recheck the system for leaks while the engine is running.
