Solution

1. Preparation

Gather necessary tools and parts, and ensure the vehicle is parked on a level surface with the ignition off.
Tools Required:
- OBD-II scanner
- Socket set
- Torque wrench
- Power steering fluid
- Pressure gauge
- Wheel alignment tool

2. Address Fluid Issues

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 recommended type of power steering fluid until it reaches the proper level.

3. Repair or Replace Components

Inspect and Replace Steering Pump if Necessary:
- Disconnect the battery to ensure safety.
- Remove any components obstructing access to the power steering pump.
- Disconnect fluid lines from the pump using a wrench.
