Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shocks.

2. Inspect and Replace Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check fluid level; top off with the recommended fluid if low.
If fluid is dark or contaminated, proceed to replace it.

3. Inspect Drive Belts

Visually inspect the drive belts for any cracks, fraying, or glazing.
If damaged, remove the belt by loosening the tensioner pulley.
Replace with a new belt, ensuring proper alignment and tension.

4. Replace Power Steering Pump (if necessary)

Remove the power steering fluid reservoir if obstructing access to the pump.
Disconnect the hoses from the power steering pump; use a drain pan to catch any fluid.
Unbolt the power steering pump from the engine and remove it.
Install the new pump by reversing the removal steps, ensuring all connections are secure.
Refill the power steering reservoir with fresh fluid.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and allow it to idle.
Turn the steering wheel lock-to-lock to bleed any air from the power steering system.
