Power steering pump replacement

It's mounted to the back side of the engine on the passenger side, marked as #1 in the picture. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Is it hard to steer in one direction, as opposed to the other? Is it a noise concern?

If it is hard in both directions, that could indicate a total loss of pump pressure. Since a PS pressure gauge is almost unheard of, you have no real way of determining precisely what is causing the problem. If the hoses/lines are not kinked or damaged, I would replace the pump first.

I can tell you with the best of my resources. Do you have access to a pulley remover and installer?
