i rented the two items from autozone that you mentioned as getting the job done in 20 seconds, but the stock jack doesn't allow the screw on the balljoint press to clear the concrete.....i take it you did it on a lift, likely? if you did use a jack, do you have any idea what the maximum lift was on it? my hydraulic just took a dump on me (for the last time) and i need to go buy another pump jack. thanks.
