Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted if needed.
Disconnect the battery to prevent electrical short circuits.

Tools Required:

Socket set
Torque wrench
Fluid catch pan
OBD-II scanner (if needed)

2. Check and Replace Power Steering Fluid

Sub-steps:
1. Remove the power steering fluid reservoir cap.
2. Inspect the fluid condition; it should be clear or light amber. If dark or contaminated, proceed to replace it.
3. Use a siphon pump to remove old fluid from the reservoir.
4. Refill with the manufacturer-recommended power steering fluid.
5. Start the engine and turn the steering wheel from lock to lock to circulate the fluid, then check the level again.

3. Inspect and Replace the Power Steering Pump

Sub-steps:
1. Disconnect the power steering pump belt using a socket set.
2. Remove the pump mounting bolts with a socket wrench.
3. Carefully detach the power steering lines from the pump, using a fluid catch pan to collect any leaking fluid.
4. Remove the old pump from its mount.
5. Install the new power steering pump, following the reverse order of removal.
6. Reconnect the power steering lines and ensure they are secure.
7. Reinstall the belt and adjust to the proper tension as per manufacturer specifications.

4. Bleed the Power Steering System

Sub-steps:
1. Fill the power steering reservoir to the appropriate level.
2. Start the engine and let it idle.
3. Turn the steering wheel from lock to lock slowly, allowing the pump to purge air from the system.
4. Monitor fluid levels and top off as necessary, repeating the process until no air bubbles appear in the reservoir.
