Morning Leary

Brian is right on the mark - if those things aren't balanced just right you're going to get vibration/shimmy. I've been through the U-joint thing twice now and if that's it, the vibration will be fairly low frequency and you'll feel it throught the seats, floorboards, and the shifter if you rest your hand on it while driving though those speed ranges. Be advised, a damaged or failing u-joint may not always be readily visible so take your time with inspecting those. Good Luck.
