2003 2500 SWB Running 35’s. For no apparent reason I developed this shake/vibration. Most noticeable in the seats, not steering wheel. During acceleration at 40-50 MPH and then above 75 MPH. Checked tires, running true (not out of round) and balanced. U-joints “appear” to be Ok as they are tight with zero slack. this vibration came from nowhere. No off-road. No mud. No towing. Just simply everyday driving. Is also very noticeable when at highway speed, simply take foot of accelerator, as truck slows, no vibration until 50 MPH through 40 MPH. Disappears as soon as truck slows below 40 MPH. What should I look at next? Vibration/shake is not noticeable at any other speeds. Thanks.
Vibration At 40-50 MPH And 75 MPH +

means nothing, pull the driveshaft and actually twist them around. see if any are seizing up
Thanks for the prompt reply. Will inspect again. Hell, its a simple job. Will replace both u-joints and update this post.
The greasable joints are hollow, and it makes them much weaker, so they un-intuitively don't last as long.
for one, as dave said, for two, thats what factory ran and they absolutely hold up the best in a myriad of different usages of the truck.
