Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the vehicle's battery to ensure safety.

2. Inspect Power Steering Fluid

Locate the power steering fluid reservoir.
Check the fluid level; if low, top off with the manufacturer-recommended fluid.
Inspect the fluid for contamination or discoloration; replace if necessary.

3. Electrical System Check

Reconnect the battery and use an OBD-II scanner to retrieve any error codes.
If codes are present, note them down for further diagnostics or repairs.

4. Test Electric Power Steering

Reconnect the battery and start the vehicle.
Turn the steering wheel while stationary to assess if the stiffness persists.
If it remains stiff, proceed to test the electric power steering motor by checking voltage and resistance as per manufacturer specifications.

5. Inspect Steering Components

Raise the front of the vehicle and secure it on jack stands.
Visually inspect the steering rack, tie rods, and joints for wear or damage.
If any components are worn or damaged, replace them as necessary.

6. Check Alignment and Suspension

Use an alignment tool to check the front-end alignment settings.
Inspect suspension components (shocks, struts, control arms) for proper function.
Adjust or replace any misaligned or damaged components.
