Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid electrical issues during the repair.

2. Inspect and Replace Power Steering Fluid

Remove the power steering reservoir cap.
Use a turkey baster to extract old fluid from the reservoir.
Refill with the manufacturer-recommended power steering fluid (check owner's manual for specifications).
Replace the reservoir cap securely.

3. Replace Power Steering Pump (if faulty)

Tools Required: Socket set, torque wrench, fluid catch pan, power steering fluid.
Disconnect the negative battery cable.
Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump hoses (use a fluid catch pan to collect any leaking fluid).
Unbolt the power steering pump from its mounting bracket.
Install the new power steering pump and secure it with bolts (torque to manufacturer specifications).
Reattach the hoses and the serpentine belt.
Reconnect the battery.

4. Bleed the Power Steering System

Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
Check the fluid level and add fluid as necessary.
