My 99 5.2 5 speed dak has 103K on it, I recently had to have my rear end rebuilt so I decided it might be time for the u-joints to be serviced.
I had a neighbor press both out and I put the new ones in, now I have a huge vibration at 65MPH.
Do you have to line the driveshaft up with the front yoke the way it came out???.
I did not mark the way it was, but I assumed both were balanced independant of each other.
Does the rear have to in the way it came out?

You didn't say if you took yoks off but I would guess you did remove 1 yoke with out marking it. I would suggest you either remove shaft and rotate it 180 degrees and see if it gets better or to test balance try attaching hose clamps to shaft with screws 180 degrees apart and see if it gets any better you may need to have shaft rebalanced.

The driveshaft has to go back on the way it came off. Check and make sure the wieght(s) to balance the shaft were not knocked off.
