The you tube videos lie- - - -or to be charitable, the folks posting them don't know their butts from third base. When original equipment studs are installed, they're pressed in, and then the ends of the splines are peened with a special tool and a pneumatic hammer to assure they don't back out if the lug nut gets loose. In some instances, the brake drum is also retained by the peened-over spline, usually on front hubs. There is a special core tool cutter that's supposed to be used to cut the swaged area away before the stud is removed to prevent the expanded section from damaging the hub or axle flange on the way out. Then a new stud is pressed in with either a big C clamp and a deep socket, a ball joint press tool, or a hydraulic press, and swaged into place again with an air hammer and the correct tool. Pulling a stud in with a stack of washers and a lug nut can over stress the thread and stretch it, making it susceptible to breaking. You Tube videos are worth what it costs to watch them, in a lot of situations. Don't bet your life on them.
