Power Steering Pump

I am going to be replacing my power steering pump on my 1989 Comanche 4.0. Autozone uses Atsco rebuilt pumps and Advance uses Cardone rebuilt pumps. Has anybody got any advice as to which are better? Should I look for a pump from another rebuild company?

Thanks...........

I would suggest new and not rebuilt, unless you just like to change parts over and over. The problem with "rebuilt" parts is that they usually just repair whatever failed and throw a little paint on it. Check out prices from the dealership, sometimes they are fairly reasonable. But wherever you get one, buy new.
