Easiest way is to removed the ps/vacuum pump still attached together. I've had mine off probably 4 times due to first a ps pump going bad then dealing with leaks... took over an hour the 1st time, now not even 15 mins If you didn't get the pump yet, be sure to get one with the sprocket on it and not have to pull your old one and press on the replacement. I got my pump from napa and it came on it already. As far as the seal kits for the vacuum pump... mines been done 3 times, still leaks
