We recently purchased a 1997 Chrysler town & country, 7 passenger van. It has a vibration that starts at 65 mph whether accelerating or not. When sitting in the back seat, the noise is louder and it sounds like the tires are bouncing. 8 different mechanics have looked at it and can find nothing. We have changed all the brakes, pads, rotors, drums, brake cylinders, brake springs, calipers, even had the new drums turned to be sure, replaced both front axles, tried 2 sets of new tires, bought new wheels, changed rear shocks, had several tire balancing incuding road pressure balancing, checked the motor and transmission mounts. We even had a transmission shop verify the transmission is OK. When we purchased it, we noticed an odd tire on the back. Had the mechanics look for damage, but they couldn't find anything on the van to suggest previous damage. Any ideas??? Thanks
