Dang!!! Only three things I can think of that would cause that,
(1) wrong bearing (as in center wrong size (allowed bearing to move))
(2) Bad trans and engine mounts (not likely but possible)
(3) defective bearing (locked up)

I don't have one out to inspect it but I did go out and look at mine, and checked my NAPA web site, and don't see any difference as in a front or rear to the bearing.

I know this is no help but maybe it will get it back to the top for sharper brains, and eyes to see it..
