Weird vibrations

Truck will all of a sudden start a vibration out of nowhere..regardless of what gear it is in..(5 spd tourqueshift)..but i will hit a bump in the road then it stops until the next bump..i feel it in the driveline but does not appear to be a trans issue..stops when i stop completely..my center drifeshaft support bearing has 1/8 -1/4 in play in rubber grommet around bearing..u joints seem fine🤔🤔..has anyone had a similar exp? I will prob change out support bearing since they are reasonably priced..any other suggestions?? 03 f350 4x4 with 143,000 miles

Check all bearings, joints and shafts,
It should not look like this

A vibration can occur under load from a misfire caused by a faulty injector or wiring chafe for examples.
Did you check for codes using Forscan or a quality scanner?
