Otherwise, I would bring it back and politely suggest that it developed a problem between the time you brought it there and when you brought it home. If it is a simple weld job, they might just do it from a customer service perspective, or to avoid any unpleasantness. When I was a shop manager, I would gladly trade a small repair (that the owner believed our shop caused) for a happy customer. Even something I knew was not our fault, I would be willing to repair , if it were a labor only proposition.
