Update,
Talked with Jim Maxey last night about what was happening with the drive line. He said he’d come over a check it out in the morning. After checking it out, we did some adjustments to the rear, and decided to try it out.
Went for a drive tonight,I am happy to say that the vibration and the roar is no more.

Thanks for everyone’s thoughts and input.

Not mentioned the drive shaft was sent out to be checked for balance. They said all they did was rotate the slip joint 180 degrees. He brought the drive shaft with the rear end to me. First thing I noticed was the shaft was assembled 1 tooth out of phase.
