Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, power steering fluid, tire pressure gauge.
Safety Warnings: Ensure the vehicle is on a level surface and the engine is off before starting work.

2. Address Power Steering Fluid Issues

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and check fluid level. If low, fill with the recommended fluid type as specified in the owner’s manual.
3. If the fluid is dark or contaminated, consider flushing the system.

3. Replace Worn Steering Components

Sub-steps:
1. If any steering linkage parts are worn (e.g., tie rods), use a socket set to remove the defective components.
2. Install new parts and torque to manufacturer specifications.
3. Ensure proper alignment of the steering system post-repair.

4. Calibrate Steering Angle Sensor

Sub-steps:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Follow on-screen instructions to recalibrate the steering angle sensor.
3. Clear any error codes and confirm calibration success.

5. Check and Adjust Tire Pressure

Sub-steps:
1. Use a tire pressure gauge to check the pressure on all tires.
2. Inflate or deflate tires to the recommended specifications found on the driver’s door jamb.
3. Inspect tires for uneven wear and rotate or replace as necessary.
