The power steering pump needs to be bled. Raise the front wheels off from the ground and remove the power steering cap. Making sure the level is correct, slowly turn the steering wheel from full left to full right several times while you monitor the fluid level. Do this with the engine OFF! Then start the vehicle and let it idle for a bit without ANY load. That should do it.
