Did you ever play with one of those old metal slinky toys when you were a kid? Do you remember that metalic sound they would make as they wound their way down a set of stairs? Well my 126 makes a similar type noise when I begin to accelerate and then again as the car slows down. I'm new to this so I thought I would consult the experts. Does anyone know what that noise is? Is it a huge problem? How do I fix it? Thanks. Rick
