Heh. If you may recall Robert I had this exact same problem happen to me last fall while driving over some railroad tracks. If the mount was original, thats your problem. For some reason, the original mounts are very weak, and have a tendency to break. The venders sell replacement ones which are much stronger. So quit trying to figure out why it broke. And this goes to ANYONE who isn't sure about this matter. Check your engine comparment and inspect the upper muffler bracket on the passenger side of the car (above the alternator) If it has been replaced, it is probably black and made from solid formed metal. The originals were thinner and had curved edges. If this is the case in your car, look carefully at it and you'll probably see some fatiuge cracks. Replace it. Better now than when it breaks. --- In dmcnews@xxxx, DMCVegas@xxxx wrote: > While moving cars around in my driveway, I heard a nasty > tapping sound in the engine compartment.
