Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fluid catch pan, replacement power steering fluid, and a flashlight.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues while working on the steering system.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir, typically found near the engine.
Remove the cap and check the fluid level; if low, top off with manufacturer-recommended power steering fluid.
If the fluid appears dark or contaminated, drain the old fluid:
- Place a fluid catch pan under the vehicle.
- Disconnect the return hose from the steering pump and allow the old fluid to drain completely.
- Reconnect the hose and fill the reservoir with fresh fluid.

3. Repair or Replace Power Steering Pump (if necessary)

If the pump is found to be defective:
- Remove the serpentine belt from the power steering pump by loosening the tensioner.
- Disconnect the power steering lines from the pump.
- Unbolt the pump from its mounting bracket and remove it.
- Install the new power steering pump by reversing the removal steps, ensuring all connections are tight.

4. Address Steering Rack Issues

If the steering rack is damaged:
- Raise the vehicle using a jack and securely place it on jack stands.
- Remove the front wheels for better access.
- Disconnect the tie rod ends from the steering rack.
- Unbolt and remove the steering rack from the vehicle.
- Install the new steering rack, ensuring correct alignment of the tie rods.

5. Reconnect Battery and Test

Reconnect the battery and start the vehicle.
Turn the steering wheel from lock to lock to allow the new fluid to circulate.
Check for any leaks around the pump and rack after the system is pressurized.
