Help, My power steering pump has been bleeding for about a week, I replaced it with a new one and today came out to a huge puddle!! What is wrong, the only thing I can think of is the plug on the back of the pump, it is the same bolt that tensions the whole unit. Replaced the pressure hose as well. Any thoughts? Is there another way to re-mount these without using that back bolt? '84 K5 Chevy in my blood.
