There's no visible cracks to be seen around the seating area, but I'll soon check how they are holding.
WOAH? 3 foot and you couldn't break em? what the? either they OVER torqued more then your saying or you didn't apply enough force yourself.
I use the air impact to tighten and loosen lug nuts all the time, its very easy to not over tighten (you have to not be an idiot), go evenly across. Most people working at these places are obviously not the brightest of the bunch, there is a reason they are willing to take these low paying jobs or settle for them, unless your an underachiever.
