Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, tire pressure gauge, torque wrench.
Ensure the vehicle is parked on a level surface and the engine is off. Disconnect the battery to prevent any electrical issues while working on the steering system.

2. Inspect and Replace Power Steering Fluid (if applicable)

Sub-steps:
1. Locate the power steering reservoir.
2. Remove the cap and check the fluid level. If low, add manufacturer-recommended power steering fluid.
3. If the fluid is dirty or contaminated, siphon out the old fluid and replace it with clean fluid.

3. Test Electric Power Steering Motor

Sub-steps:
1. Reconnect the battery.
2. Use a multimeter to test the voltage at the power steering motor connector.
3. If the voltage is within specifications, the motor is likely functioning correctly. If not, consider replacing the steering motor.

4. Inspect Steering Components

Sub-steps:
1. Visually inspect the steering column, linkage, and tie rods for any signs of wear or damage.
2. If any components are damaged, replace them as necessary.
3. Reassemble and ensure all connections are torqued to manufacturer specifications.

5. Align Steering Wheel

Sub-steps:
1. If the steering wheel is misaligned, use an alignment machine to correct the angle.
2. Adjust the tie rod lengths as needed to ensure proper wheel alignment.
