well nothing else has changed except the shaft...i had a whinning in the rear, and we all knew it was the gears, but my boss suggested i rebalance the driveshaft and i did, and i put new u-joints, and i put it back in and the whine has not changed, but now it vibrates at speed...and i know its not wheels, it is something in the drivline specifically transmission to rear..yea there isnt play up and down, i was under it for a while today...the only thing i noticed, is with it jacked up and it in nuetral, i can turn the driveshaft maybe a half inch in either direction before the wheels will move
