Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery before working on electrical components.

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 power steering fluid (usually Dexron III or equivalent) until it reaches the proper level.
Inspect for any visible leaks around hoses and connections.

3. Inspect and Replace Power Steering Pump (if necessary)

Remove the serpentine belt by loosening the tensioner pulley with a socket wrench.
Disconnect the power steering pump from the vehicle by removing the mounting bolts.
Detach the power steering lines using a line wrench to prevent damage.
Install the new power steering pump in reverse order, ensuring proper torque on mounting bolts (typically around 16-22 ft-lbs).
Reconnect the power steering lines and refill the system with fluid.

4. Inspect Steering Rack and Tie Rods

Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack for any damage or leaks.
Check the tie rods for any excessive play by moving them back and forth.
Replace any damaged components as necessary, following the manufacturer's specifications for torque.

5. Test the System

Reconnect the battery and start the engine.
Turn the steering wheel from lock to lock to bleed any air from the system.
Check fluid levels again and add if necessary.
Take the vehicle for a test drive to ensure proper steering function and verify that the issue is resolved.
