Woops

So last night I was replacing the wheel bearing in a truck right... well I was having fun putting the truck back together (and this was after even more fun getting it apart) when I decided to use a 2x4 to prop up the spring arms to push the pieces back together (trying to keep the explanation non-technical here), while I lowered the lift a few inches. Well so apparently it took more force to lift that spring arm than the truck weighed and the 2x4 started shifting the whole truck off the lift!! Yeah so that was my excitement for the week (the year?).
