vibration/ droning type issue

[forerunnin]

I have an issue that is driving me crazy. I have a vibration that starts around 30 miles an hour then kind of goes away for little bit then comes back around 45 ,then minimize again and comes back around 60 . the whole vehicle vibrates ,I installed 4 new tires and that did not seem to fix the issue . its unbearable at times, kind of like when your child rolls the window down in the back and you get that droning vibration humming type of thing . I don't believe it's the front end because there is very little vibration in steering. The vibration stops as soon as you let go of the gas and comes back when you step on the gas . I'm lost. Help please.

Could be U joints in the driveline or the pinion angle is not ideal. If you haven't had an alignment on the wheels I woud take it in and mention the vibration issue to the alignment shop.

Bad U-joints are usually more of a clunk, but definitely worth checking.
