Good luck!!!
Interesting. So, since my center bearing looks fine (it could be binding but nothing says it is), I suspect IF it is driveline related, it would be the u-joint.

Does your driveshaft have a u-joint? I’d suspect that in your case, maybe the slight change in angle caused the bearings to sit and roll slightly different. It seems like my best option is to pull the driveshaft (I’m assuming shimming would just be some washers on the bolts?), versus dropping the thing. But isn’t it prudent to check all the components for binding?
