Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shocks.

2. Inspect Power Steering Fluid

Remove the power steering fluid reservoir cap.
Inspect the fluid for contamination or a burnt smell.
If the fluid is low, fill it to the recommended level with manufacturer-approved fluid.

3. Replace Power Steering Pump (if necessary)

Tools Required: Socket set, wrench set, power steering pump pulley puller, fluid catch basin.
Remove the serpentine belt by releasing the tension on the belt tensioner.
Disconnect the power steering lines from the pump (use a fluid catch basin to collect any leaking fluid).
Unbolt and remove the power steering pump from its mounting bracket.
Install the new power steering pump in reverse order, ensuring all bolts are torqued to manufacturer specifications (typically 18-25 ft-lb).
Reconnect the power steering lines and replace the serpentine belt.

4. Bleed Power Steering System

Fill the power steering system with fluid to the proper level.
Start the engine and turn the steering wheel fully left and right several times to allow air to escape.
Check fluid levels again and top off as necessary.
