Nasty Vibe remains
I'm getting a nasty vibe when accelerating through the gears. It's starting to vibrate through decelerating too. I'm trying to brainstorm what it could be. There are no track bars or a sway bar. I'm thinking it's a u-joint going bad because there's a light metallic scraping noise coming from the rear end. Might be a cap going bad or something? The tricky part is the vibration is intermittent so I think that would rule out it being in the pumpkin. I don't know though, any other ideas?

Tcase drop installed
No clinks clanks or thuds when shifting. Goes in every gear just fine. Thought about the transfer case too but that shifts fine as well. Rear driveshaft is still pretty tight.
Also thought about a pinion bearing but when the vibration goes away, the noise pretty much does too. I would think if a bearings going then the noise would be constant. Not sure though.
Sometimes this vibe is REAL nasty especially when accelerating - shakes the whole vehicle.
