I have a pretty healthy power steering leak on a 92 400E, about 18 inches behind the pump. It looks like a bad low pressure rubber hose towards the back of the system. So I'll just replace it. But preliminarily I have concluded a) no access frrom below and b) no access from above. It's impossible from below, they must be thinking from above. But it's very tight and there's an engine guard very much in the way, and it's a very large engine guard that is not going to move easily. Am I on the right track? Am I going to have to raise the engine?
