For stubborn, seized suspension parts or rusted brake drums that won't budge with a standard hammer, you need a sledge hammer. Often called a club hammer or hand sledge in its short-handled version, it features a heavy steel head (typically 3 to 4 pounds) that delivers high-impact force. Use it with a block of wood or a brass drift to avoid denting or cracking the steel parts you are striking. Swing with control and keep your hands clear of the rebound path.
