Off and on I get this horrible vibration from the rear end of my car. Last about 5-10 seconds each time. It's only when I go to spped up (Ihave an auto) and floor it then it just shakes real bad and sounds like i'm driving over rumble strips. I think it just might be tthe u joints any one have any input?

usually when its the ballancer is the motor that shakes. Take a look at the ballancer and check if you can see anything sticking out of it or not. Also does your shifter shake when it vibrates? Mine did that when my U-Joints went bad.

Easy check. Jack up the car, put transmission in 1st gear, ebrake set, and turn the driveshaft back and forth & look for excess play. It should turn very slightly, but that is it.
Visually examine your u-joints. Have you seen a u-joint un-installed? It looks like a "plus sign" (i.e. +). At each end are cylindrical metal caps which are pressed into the driveshaft yoke. If it looks like one of the "arms" of the u-joint are broken, you need to replace it.

I had a real big vibration in the car when I would gas it and I went and had my back tires static balanced and it went away. Even at about 75 mph, it had the vibration. Check that first. Could be a cheap fix.

Cheaper test is to rotate them front to back.... if the vibration moves to the front... you know where to look.
