I never posted in this forum and we have been getting a strange vibration in our van. So I thought I would post to see if any of you out there might have an inkling of what it could be. We have a 1999 Ford E-150 Conversion van. It just hit 75,000 and runs well. We maintain it as much as possible as we have had it three years and would like to see it last at least another five or more years. Or even longer if possible. Back in november we had the Ford dealership replace the two front tires as the van really needed tires. But being on a very fixed income, we couldn't do all four but did the front as they seemed to be the worst.We also replaced brake pads, and dealership said we would need rotors in near future. I think we were already getting the vibration at that point. I really can't remember. A month later we took the van to a small shop which was highly recommended close to home and had the rear tires replaced. We also had the rotors replaced at this point, and also had to redo brake pads. This peeved me because if I knew it was recommended replacing the pads when you do rotors, I wouldn't have waited and ended up buying two sets of pads. Still getting vibration. Brought van back to dealership, and they said its the rear tires. Have the guy who put them on rebalance them. I didn't think it was from the back, but DH brought the van back to the small garage and the guy couldn't see anything wrong with rear tires, but balanced them again anyway to make sure. Still getting vibration. And now getting frustrated. Vibration seems to be in the front, and is through the van, not a vibration just in the steering wheel but it seems like the whole front end shakes. And only when were doing about 55-60 miles on the highway. Lower speeds it seems to smooth out. Also, when someone is sitting midship they can feel the vibration. Any ideas? Bad tires? Ball joints? U-joint or something? (my brother mentioned something but I can't remember it) THANKS!
