Solution

1. Preparation

Gather necessary tools: OBD-II scanner, torque wrench, jack and jack stands, multimeter, and basic hand tools.
Ensure the vehicle is parked on a level surface and the ignition is off.

2. Inspect Power Steering Fluid Level

Locate the power steering fluid reservoir.
If applicable, remove the cap and check the fluid level against the dipstick.
Top off with the recommended type of fluid if low. If empty, look for leaks in lines or fittings.

3. Check for Fault Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn the ignition to the "On" position without starting the vehicle.
Scan for any error codes related to the steering system and record findings.

4. Inspect Steering Components

Lift the front of the vehicle using a jack and secure with jack stands.
Inspect the steering rack for any play or damage.
Check the tie rods and control arms for wear or damage; replace if necessary.
Torque specifications for tie rod ends should be checked as per manufacturer specifications.

5. Test Battery Voltage

Use a multimeter to check the battery voltage.
A healthy battery should read around 12.6 volts when fully charged.
If the voltage is low, recharge or replace the battery to ensure proper power to the steering system.

6. Final Assembly and Testing

Reassemble any components that were removed during inspection and ensure all fasteners are torqued to specifications.
Lower the vehicle and conduct a steering test by turning the wheel to check for improvement.
