I think I’ve found my problem. One rear bearing is shot, and all three rear bearings are frozen in their carriers. Can’t get them out or to even move. I also went over the frame by look and feel and found no cracking. There was a slight deformation under one of the motor mounts where it’s crushed a tiny bit but that’s it.
Thanks for all your help guys. I’m going to replace these bearings and see where that gets me.
