Solution

1. Preparation

Tools Required: Socket set, wrench set, fluid catch pan, OBD-II scanner.
Park the vehicle on a level surface and turn off the engine.
Allow the vehicle to cool down if it has been running.

2. Check and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering fluid reservoir.
2. Remove the cap and dip a clean stick to check fluid level.
3. If low, add the recommended power steering fluid (refer to the owner's manual).
4. If the fluid is dirty or contaminated, drain and replace it.
5. To drain, place a fluid catch pan under the pump, disconnect the return line, and allow fluid to flow out.
6. Reconnect the return line and refill the reservoir to the proper level.

3. Inspect and Replace the Power Steering Pump

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical shorts.
2. Remove any components obstructing access to the power steering pump (e.g., engine covers, hoses).
3. Disconnect the power steering lines from the pump using the appropriate wrenches.
4. Remove the pump mounting bolts with a socket set.
5. Carefully take out the power steering pump from its bracket.
6. Install the new power steering pump by reversing the removal steps.
7. Reconnect the power steering lines and tighten to the manufacturer's torque specifications.

4. Bleed the Power Steering System

Sub-steps:
1. Refill the reservoir with new power steering fluid.
2. Start the engine and turn the steering wheel from lock to lock several times to remove air from the system.
3. Check the fluid level and top off as necessary.
