[Classic Heartbeat]

Just an FYI, I have had 2 customers come in that have had the bolts pull through the floor using urethane mounts. Granted these were 4X4s and there frames probably were flexing more than a 2WD. However the facts are you have a flexible chassis and you can't change that without boxing it. Urethane bushings are not flexible, not even a tiny little bit. Now consider that your cab in spot welded together making it non flexible. At least to the point when it does flex the metal starts to fatigue. It fatigues around the spot welds in the areas that the cab is forced to flex, eventually splitting the metal. Eventually you start hearing rattles and pops, and if the problem is not addressed things finally brake. This is why in any application where a flexing or vibrating part is mounted to an inflexible part, rubber bushings are installed. WES
