My Bronco II vibrates under power only. If I take my foot off the gas, the vibration stops. If I coast down a hill, no vibration. The vibration is worse in first, and gets better as I shift through the gears, but it's still there none the less. U-joints seem fine. Since it only does this under power, I don't think that it's the tires, wheel bearings, differentals, or drive shaft. If anyone has any ideas, I'd really appreciate it.
