You can take a look at your slip yoke and see if there is any burn/wear marks on it..or if you notice it is smooth as glass and uneven wear
I would also inspect the tailshaft bushing very closely make sure its not worn or damaged.
Bingo!
The driveshaft looked fine to the eye, but maybe an end bell is slightly bent?? I pulled it again to re-asses the yolk like you said, and it does have discoloration around an uneven polished area. . It is slightly worn more on one side, but I have to really look to notice it, more of a feel it than see it type of wear.
I guess I need a new driveshaft and tailshaft bushing. Since this is a donor car for my project I have a reason to get an aluminum driveshaft because it will go to better use later
Thanks for the help everybody!
Thanks Tony!
Updates on the problem when I get a new driveshaft for it in a month or so. I have to fix the a/c in my wife's car and take my truck back. Then I can justify spending on this since it's a little more than I wanted to spend on it in the first place. Fixing her car is going to be cheaper at this point, so that is the logical thing to do here.
