After a month and a half, the driveline is holding up very well but, a vibration has emerged from somewhere. It starts at about 55-60 mph and worsens with speeds above that. It's my guess that the driveline is binding at the front joint. After the tranny swap, the rear driveline was lengthened and rebalanced with new u-joints (1350's) and knuckles on both ends. Fluid level is good in both the transfer and rear end..

Anybody a driveline expert that may have some input? Tried to get a couple of pics. Can get more if needed just let me know what you need to see.
