Developed a roar...
There's one aspect of the driveshaft that I've read about, but haven't had to work with and it's the orientation of the u-joints(not sure of wording)when taken out and then put back in. They must be re-installed on same plane between the two drive shafts. This is more of a question than an answer.
and if you drive it that way it can also cause "irreverseable damage"
