Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the 12V battery to avoid any electrical issues during repairs.

2. Inspect Power Steering System

Tools Required: OBD-II scanner, socket set, torque wrench.
Check the power steering fluid reservoir for adequate levels; top off with the recommended fluid if low.
If fluid is contaminated, drain and replace with fresh fluid.

3. Check Electrical Connections

Inspect the wiring harness and connectors leading to the power steering unit.
Look for frayed wires, loose connections, or corrosion. Repair or replace any damaged components.

4. Inspect Steering Rack and Components

Remove the front wheels using a jack and jack stands for access to the steering components.
Visually inspect the steering rack, tie rods, and control arms for wear or damage.
Tighten any loose bolts to the manufacturer’s torque specifications.

5. Test Drive and Alignment

After repairs, reassemble any components removed during inspection.
Conduct a test drive to observe steering response and check for any residual stiffness.
If necessary, perform a wheel alignment to ensure proper steering geometry.
