Vehicle runs and feels fine under 40 mph or so. On the highway once you start accelerating there is a very pronounced vibration in the front end. Starts at about 50 mph or so. Difficult to nail down one side or the other. If you back off the gas, the vibration almost disappears. Seems more pronounced with a fully loaded vehicle. Uphill or down no difference. Vibration disappears around 65 mph.
Motor and tranny mounts were bad, so I replaced those. No difference. Front tires are balanced as well. In fact, most of the front end parts have been replaced within the last 24 months or so. Any ideas?

Check the struts for signs of oil leakage. If you know how to do it carefully, you can jack up one front wheel by the control arm, (to keep the suspension system in its normal geometry), and run it in gear. This will let you see a bent wheel or hub. It also might show up a severe out-of-balance problem although sometimes this can be misleading because vibrations can be set up when there is no problem with that wheel.
