E-450 Viberation
I have a 2000 Winibago E-450. I have a bad viberation at 40MPH. It has new tires front and rear. It does not feel like the front, I don't feel it in the steering wheel. Faster then 45MPH it seems to g...

Did you just get this coach and notice the problem, or have you had it awhile and now the problem has developed?
U-Joints work well, only when they're pretty close to straight-on. When they have to accommodate quite a bit of angle, they accelerate and then slow the shaft. That's why modern FWD and 4WD vehicles use CV (CONSTANT Velocity) joints instead of U-Joints.
Point of this is, you need a little "off angle" for the driveshaft to NOT oscillate as if it was one long shaft. But not too much. I helped a member here with some angle measurements, and it turned out the front flange on the differential was too vertical. Rear axle needed to be shimmed so the flange came closer to the angle of the driveshaft.
All said, the Carrier Bearing(s) are big ball bearings that can go bad, but often the rubber mounting breaks down, and you get vibration.
