Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to avoid any electrical issues while working.

2. Inspect and Replace Power Steering Fluid

Tools Required: Funnel, power steering fluid (as specified in the owner’s manual).
Remove the power steering fluid reservoir cap.
Check the fluid level; if low, add the recommended power steering fluid until it reaches the proper level.
If the fluid is dark or contaminated, flush the system:
- Disconnect the return line from the power steering pump.
- Use a container to catch the old fluid as you turn the steering wheel left and right.
- Reconnect the line and fill the reservoir with new fluid.

3. Inspect and Replace Power Steering Pump

Tools Required: Socket set, wrench set, power steering pump replacement part.
Locate the power steering pump; inspect for leaks and listen for unusual noises when the engine is running.
Disconnect the power steering belt by loosening the adjustment bolt and removing the belt from the pump pulley.
Remove the power steering pump mounting bolts and disconnect the fluid lines.
Install the new pump by reversing the removal steps, ensuring all connections are tight and secure.

4. Check and Replace Steering Rack

Tools Required: Socket set, wrench set, tie rod end puller, steering rack replacement part.
Lift the vehicle and secure it on jack stands.
Remove the front wheels for better access to the steering components.
Disconnect the tie rod ends from the steering rack using a tie rod end puller.
Unbolt and remove the steering rack from its mounting points.
Install the new steering rack by reversing the removal process, ensuring that the tie rod ends are torqued to specification.

5. Calibration

Tools Required: Scan tool capable of performing steering angle calibration.
After any replacement of steering components, connect the scan tool to the vehicle.
Follow the manufacturer’s instructions to perform a steering angle sensor calibration.
