If a u-joint is causing a driveline virbration, don't ignore or neglect it. In addition to the vibration you feel, those same shock waves are raising havoc on other components such as the tailshaft bushing/bearing, pinion bearings and if equipped, carrier bearing and rubber.

Some will run a while that way, getting noticably worse, others will let go without warning, especially if the needles have fallen out. Sometimes, when they let go, there is much damage to other components attached to or nearby the driveshaft as the unrestrained end of the driveshft whips around

A friend of mine years ago lost a u-joint near the center of his box van (right behind the carrier bearing), the rear driveshaft dropped, dug into the pavement and catapulted the truck onto it's side. This was a larger box van approx 24,000 lbs GVW. His speed was 30 MPH.

My advice, get under the truck, check the u-joints and carrier bearing/rubber (if equipped) for looseness and repair whatever is loose or worn out. U-joints are cheap, relatively speaking.
