Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the high voltage battery before working on the steering system.
Gather necessary tools and parts.

2. Check and Refill Power Steering Fluid

Tools Required: Fluid pump, funnel, clean rags
Locate the power steering fluid reservoir (if applicable).
Use a fluid pump to remove any old or contaminated fluid from the reservoir.
Refill with the manufacturer-recommended power steering fluid to the proper level.

3. Inspect and Test Power Steering Motor

Tools Required: Multimeter, socket set
Disconnect the electrical connector from the power steering motor.
Use a multimeter to check for voltage at the connector when the steering wheel is turned.
If no voltage is present, inspect the wiring harness for damage or loose connections.
If voltage is present but the motor does not respond, consider replacing the power steering motor.

4. Inspect Steering Rack and Components

Tools Required: Jack and jack stands, socket set
Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the steering rack for signs of leaks or damage.
Check the tie rod ends and other linkage components for play or wear.
Replace any worn components as necessary.

5. Tire Pressure Check

Tools Required: Tire pressure gauge
Use a tire pressure gauge to check all four tires for proper inflation.
Inflate any under-inflated tires to the manufacturer-recommended pressure.
