Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical issues during repair.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.

2. Fluid Check and Replacement

Check Power Steering Fluid:
- Remove the cap of the power steering fluid reservoir.
- Inspect the fluid level and condition; replace if low or contaminated.
Replace Power Steering Fluid (if necessary):
- Use a fluid pump to extract old fluid from the reservoir.
- Refill with manufacturer-recommended power steering fluid.

3. Inspect and Replace Power Steering Pump

Removal:
- Disconnect the power steering lines using a line wrench.
- Unbolt the power steering pump from its bracket using a socket set.
- Remove the pump from the engine bay.
Installation of New Pump:
- Position the new power steering pump in place.
- Tighten the mounting bolts to the manufacturer-recommended torque specification (usually around 20-25 ft-lbs).
- Reconnect the power steering lines and tighten them securely.

4. Steering Linkage Inspection and Replacement

Inspection:
- Check all tie rods, ball joints, and rack and pinion for wear or damage.
Replacement (if needed):
- Disconnect the tie rod end from the steering knuckle using a ball joint separator.
- Remove the old tie rod and install the new one, adjusting to the same length as the old part.
- Tighten the nut to the manufacturer's specifications.

5. Steering Angle Sensor Calibration

If replaced, use an OBD-II scanner to calibrate the new steering angle sensor:
- Follow the manufacturer’s procedure to reset the sensor.
- Ensure the steering wheel is in the neutral position during calibration.
