Have you ever removed anything in the drive line that could be out of alignment left to right? Carrier bearings also see the movement of yaw.

There is no need for further discussion. If the shaft is angled, his center carrier is upside down. Nothing else can cause this.

This was the best I could find and the owner has the BMR cradle inserts. Differential movement takes place under hard acceleration. Look to the left and you see the suspension with a lot of movement.
I don't think the differential had anything to do with the bearing going bad. But I dunno. I'm a guesser.

I'm not understanding this. Isn't the driveshaft set up in two pieces because the front comes out straight from the transmission, then at the U joint it angles down toward the differential? Or at least it allows the back half to move around a little to compensate for the slight movement of the differential.

Either way, there's no way it is. It would take one really inept person on the factory assembly line. Probalby several. Quote:
I guess I should define angled a bit better. It wasn't extreme by any means. It was just higher in the biddle. But barely. Just enough to notice with the naked eye. He was talkng 3 degrees. and thinking it should be at zero or one degree. |

Ok. Well, at least the shop found my problem. So now another question. Can the rattling noise in the video be from pieces of the bearing or bearing assembly broken off and INSIDE the driveshaft tumbling around? |

Sounds possible. As minor as the angle you describe is, I wonder if just the center pilot is worn out

I'm not totally useless..

On our cars (IRS) ALL the vertical movement is taken up by the half-shafts with the diff being "solidly" (somewhat) mounted to the car (via the subframe). The driveshaft angle doesn't change to the degree your tech thinks it does (a little bit is designed in to handle the flex of the motor/trans mounts). Capiche?

I can't remember if the driveshaft is hollow, but in your other thread I said it almost sounded like a pebble found it's way in there and is bouncing around inside the driveshaft.

You know, when I hear that video, I think of the end of Kill Bill Vol #1 when they are fighting in the snow. In the background all you hear is this water well bucket thingy fill up and then dump. Sounds just like that!
I know, I know, that helps nothing.
