Rusted bolts????

that sucks especially the nut bolt thing.... I'd keep an eye on that it's easier to fix though if locks up just break off the bolt head, tap it through and buy a new nut/bolt. a bigger impact is nice but you need a bigger compressor to make it work, I had a 11 gallon compressor and could take 2 lugs off before I had to let the tank fill.... got a 30 gallon and can do all four tires before the motor kicks on.
