1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface, and the engine is off.
Disconnect the battery to prevent electrical issues.

2. Inspect and Replace Power Steering Fluid

Sub-steps:
1. Locate the power steering reservoir and remove the cap.
2. Use a turkey baster or siphon to remove old fluid.
3. Fill the reservoir with the manufacturer-recommended power steering fluid.
4. Start the engine and turn the steering wheel from lock to lock to circulate the fluid.
5. Check the fluid level again and top off if necessary.

3. Inspect and Replace Power Steering Pump

Sub-steps:
1. Remove the drive belt by loosening the tensioner bolt.
2. Disconnect the power steering fluid lines from the pump using a wrench (be prepared for fluid spillage).
3. Remove the mounting bolts securing the power steering pump to the engine.
4. Remove the old pump and replace it with a new unit, ensuring it is aligned properly.
5. Reconnect the fluid lines and torque the bolts to the manufacturer's specifications.
6. Reinstall the drive belt, ensuring proper tension.

4. Bleed the Power Steering System

Sub-steps:
1. Fill the power steering reservoir with fluid.
2. Start the engine and let it idle.
3. Turn the steering wheel from lock to lock slowly to remove air bubbles from the system.
4. Check fluid levels and add more if necessary.
