I feel a vague crepitus in the front end when I'm driving..almost like the power steering is low but doesn't really get more noticeable upon turning. It has been a little low a few times recently and I have topped it off. Looks like its seeping from somewhere around the pump but I'm not sure where. I replaced the high pressure hose about 6 months ago. When they fail is it all or nothing? I saw on SOR site that they don't recommend a rebuild because some machining is required. Is there another pump I can pull off a more common toyota car in a junk yard?
