Too Much Pinion?

-
The first question that comes to mind is, "Has the driveshaft angle & the pinion angle been checked?"
 
OMFG!!! He has the diff hanging in the air. Which puts the u joints into a bind. He has been told to put it on jack stands under the diff to simulate the suspension being loaded. Kim

Super quick update:

when i turn the tire by hand, 3/4 of the rotation of the yoke is smooth, then come to a hard stop. If I really push the tire/yoke will complete the rotation. It could be a cap in the yoke? Nothing is physically binding and I don’t think the pinion angle is wrong, it’s something with the u joint. Thank you for all the help and o”pinions”!

Pinion angle may not be wrong when the suspension is loaded. But unloaded it it outta wack and put in a binding situation. Can u understand that? And comprehend it? If not get someone to help that does. Your your own worst enemy. Dam, I’m turning into RRR. Kim
 
:popcorn:
jack stands check!
rotation check!
check pinion angle check!
pull driveline check!
check driveline yolk check!

nice n clean looking ride! check!
 
Found the issue, bump out from the grease fitting was hitting pinion nut. Will see if it’s possible to reverse the u joint and load the car on the 8 3/4 next time during the warm up. Live and learn. Thanks so much for the input. I didn’t see the rubbing until I loosened the u joint/driveshaft.

Yup. I agree. If he's done it yet, I haven't seen him post.

Try putting the jack stands under the rear housing to support the car's weight on the the suspension and turn the tires again. You will likely not have a problem.

I wonder if you have enough meat there to shave off a little. With full weight on the suspension it may go away, but to gain peace of mind a shave might relieve it altogether. ya?

but consider checking pinion angle when differential is on jack stands ie full weight on suspension.

I certainly will. Hope to solve this sometime tomorrow. There’s just never enough time to work on it consistently. The jack stands will get moved when I try again.
 
Finally got some time to give some closure to the issue. Yes I didn’t have the car supported properly and that was contributing. The ultimate issue was the bump out on the yoke. It has since been reversed and installed. Everything runs smooth. Thank you for all your help and patience. I get it. It’s frustrating when someone doesn’t do something the right way. Thanks again Fabo community.
