    Took of the tranfer case(208) on my 86 K5 to repair an oil leak. Everything worked out fine exept that now at certain rpm's or accelarating I have some vibrations from the drivetrain that I didn't have before. I only run a 2 1/2" lift so I don't think the driveshaft angle is the problem. I did notice last night that where the rear u-joint is bolted to the differantial yoke sits a little further to one side, can that cause the problem.

    yes, you have to get the ujoint centered in the yoke, if not, the ujoint could loosen up and become unattached while you cruise aglong at 70 down the highway. in other words, i would fix that soon unless you want a driveshaft in your backseat.
