As soon as I slid the wheel off of the lugs, the jack started failing. A seal gave out and the truck slowly started dropping. My father started pumping the jack to try to keep it up, but with every pump, it would fall a little faster. So, he was pumping away as fast as possible while I was trying to get one lug nut started to hold the wheel on.
That was enough to scare me.
Sorry about straying off topic.
