Was the driveshaft indexed before you took it out to put the u-joints in? If not, pull the bolts of the rear, flip the driveshaft 180 degrees and reinstall.

Check out THIS THREAD for more info.

Did you check the contact patch and engagement on the ring/pinion when you set up the rear?

Just trying to cover the basics. I have no clue what a contact patch or engagement is and Kyle knows his stuff...The only experience I have with a vibration and u-joints is a driveshaft that isn't indexed.

Hope you find the culprit!

So does that mean that you didn't check back lash, etc either?

THIS LINK should provide you with the required setup for a rear end to maximize it's life.

That is just the first thing I found that had the steps. There are better pages that detail things better if you search around the internet a bit more.
