Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter.
Disconnect the vehicle's battery to ensure safety during repairs.

2. Inspect and Replace Power Steering Fluid

Check Fluid Level: Locate the power steering fluid reservoir and check the fluid level. If low, add the recommended type of power steering fluid (consult owner's manual).
Replace Fluid: If fluid appears dirty, drain the old fluid using a siphon pump and refill with new fluid. Ensure to bleed the system as necessary by turning the steering wheel from lock to lock several times.

3. Inspect and Repair Steering Column

Remove Cover: Using a socket set, remove the steering column cover to access internal components.
Check Connections: Inspect wiring harnesses and connectors for damage or corrosion; repair or replace as necessary.
Lubricate Components: If there is binding, apply appropriate lubricant to the steering shaft and any pivot points.

4. Test Electric Power Steering Motor

Reconnect Battery: Reconnect the vehicle's battery.
Use Multimeter: Test the electric power steering motor's voltage and ground connections. Replace the motor if it does not receive adequate power or shows signs of failure.

5. Check Wheel Alignment and Tire Pressure

Inspect Tires: Confirm all tires are inflated to the manufacturer's recommended PSI.
Alignment Check: Take the vehicle to a professional alignment shop if misalignment is suspected. Adjust as needed to ensure proper handling.
