maybe i just had a bad experience, but mine took me an entire night. We used spring compressors and they were a b!tch to get on at the right angle to where we could actually compress them. After we got them compressed as much as we could, we spent about an hour trying to pry them out with a crowbar, then repeated for the other side. That was just the front two, the back was cake though. Took prolly about 30 min to do the entire rear.
