There is a plastic insert in the bushing about an inch or so that changes it from "deep bushing" to "shallow bushing" so my mom doesn't get it right grips, rounding the edge off when I tried to apply torque. I had to take it off by driving a REAL CRAFTSMAN MADE 12 point head into the lug nut until it was strong enough to tighten, destroying what was left of the nut. I will say right away that I had to replace the mother. Stay away from that trash can.
