Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the steering system.

2. Check and Replenish Power Steering Fluid

Tools Required: Funnel, clean rag
Instructions:
1. Locate the power steering fluid reservoir, typically found near the engine.
2. Remove the reservoir cap and wipe the dipstick clean.
3. Insert the dipstick back into the reservoir and remove it to check the fluid level. It should be between the minimum and maximum marks.
4. If the fluid is low, add the recommended power steering fluid (consult the owner’s manual for the correct type).
5. Replace the cap securely.

3. Inspect the Power Steering Pump

Tools Required: Wrench set, flashlight
Instructions:
1. Locate the power steering pump, usually mounted on the engine.
2. Inspect the pump for leaks and check the hoses for any signs of wear.
3. With the engine running, listen for any unusual noises from the pump that may indicate internal failure.

4. Check Steering Column Components

Tools Required: Socket set, screwdrivers
Instructions:
1. Remove any panels or covers obstructing access to the steering column.
2. Inspect for loose or damaged bolts, especially those securing the column to the vehicle.
3. Check the universal joints and couplings for wear or binding.
4. Tighten any loose bolts to the manufacturer's torque specifications.

5. Test Steering Angle Sensor

Tools Required: OBD-II scanner
Instructions:
1. Connect the OBD-II scanner to the vehicle’s diagnostic port.
2. Read the steering angle sensor data to ensure it is functioning within the specified parameters.
3. If the sensor is faulty, replace it according to service manual specifications.
