you need to get the car up on ramps, or how ever, and start the car, with it running get under it and watch where its leaking from, if you have someone there who can turn the wheel back and fourth that will make it leak more.
if your leaking from the boots, (at the ends of the rack) just get a new rack.
could also be from one of the lines as well.
or the pump its self.
if need be, clean the engine top and bottom,( and the rack and trans) then start looking again. and a clean engine is nicer to work on too.
