Front driveline vibes

I have been getting light vibrations in the front just recently. I changed hubs & axle u joints previously so I knew it wasn't them. So I just removed the driveshaft and the u joints "look" ok but that isn't something to go off of. They are not tight or too loose. But the vibes are now gone.

So my question is since they are now gone can I rule out that it is not the pinion bearing, and rebuild the driveshaft?
Or is there another way I can see if it is the pinion bearing?
Thanks in advance.

Is there any way your driveshaft could be out, I would take it to a driveline shop and have them make sure its balanced and true.

I was thinking that also, I might grab one at the jy this weekend. The place I go usually sells "little" items including driveshafts for between 5-10 bucks.

After looking at the joints again I noticed some tight spots in the "ball" and middle u-joint. I bought the parts today and some paint and I am going to rebuild it.

All fixed. The needle bearings in one of the caps of the center u joint were rusty as hell. All put back together and running fine.
