Background I have a vibration from 65mph and up
its worse when accelerating or decelerating
both wheels have a very small amount of play when pushed at 12 o clock
there is no howling as is described with other diff problems
you can see the sound coincides with the metal moving in and out.

I took a leisurely ride last night with the wife in the Lexus (she thought we were just going for ice cream instead of a test run for noises...LOL) there is definitely no noise similar to this while moving. At slow speeds i can hear a faint high pitched squeak which I think is the wheel bearings.

The vibration at 70mph is still there, otherwise it is very quiet.

I'm thinking that when the wheels are off the ground the weight of them pulls the axles away from the differential and that pulling is allowing the bearing to move in a way to create this noise.

ya, that is not a good noise! I think your idea about the wheel bearing is probably correct.
