I have a 55 second series with an after market (Saginaw) power steering pump. I purchased a new pump from a local parts store and it leaked like mad. I received a replacement from the parts store and it is not working all the time as well as the bearing sounds like it is going out. The application in my 55 is difficult and takes a lot of time to get the pump in place. I'm looking at "on like parts stores" and find the pump at a price of around $160.00 and I just can't see puting that kind of money in a new pump. Any ideas out there?
