I've got a 1998 Dodge Ram 1500 2 wheel drive. I've had to replace the power steering pump about 3 times now. It appears to me that the seal keeps going out. I get the pumps at Auto Zone and the only reason I keep getting them there is because they have a lifetime warrantee so it doesn't cost me anything except my own labor, but it's still a pain. Has anyone else had this problem?
