Solution

1. Preparation

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

2. Check and Top Off Power Steering Fluid

Locate the power steering fluid reservoir under the hood.
Remove the cap and check the fluid level; it should be between the "min" and "max" marks.
If low, add the appropriate type of power steering fluid as specified in the owner's manual.

3. Inspect and Replace Power Steering Pump (if defective)

Tools Required: Socket set, wrench set, fluid catch pan.
Remove the serpentine belt by loosening the tensioner.
Disconnect the power steering pump hoses and allow fluid to drain into the fluid catch pan.
Remove the mounting bolts for the pump and take it out of the engine bay.
Replace with a new power steering pump, ensuring alignment with the mounting holes.
Reconnect the hoses and fill with new power steering fluid.

4. Inspect and Replace Steering Rack (if necessary)

Tools Required: Jack stands, socket set, torque wrench.
Lift the vehicle using jack stands for better access to the steering components.
Disconnect the tie rod ends from the steering rack.
Remove the mounting bolts securing the steering rack to the subframe.
Carefully slide the steering rack out and replace it with a new unit.
Reconnect all components, ensuring proper torque specifications are followed.

5. Reassemble and Test

Reinstall the serpentine belt.
Reconnect the negative battery terminal.
Start the engine and turn the steering wheel back and forth to bleed air from the system.
Check for any leaks around the power steering components.
