I just bought a 2000 Dodge 3500 cab and chassis truck. It has a leak between the power steering pump and the vacuum pump, but it also makes a groan when I am turning the truck. The weird thing is that it only groans when I make right hand turns. I have done some homework and it looks like there is a kit for the leak, but do yall think the power steering pump needs to be replaced? How much is a pump? and do you still needs a seal kit if you get another pump?
