Decel vibration between 2100-2500 RPM is the issue with my 3.73 frpp gears. Not sure if it's caused by an incorrect bearing or if it's caused by the stock driveshaft. I figure if it was the wrong bearing, it would always be vibrating and causing more noise. I made the mistake of trusting an AM rep when he said my 2011 didn't need the 2010+ bearing in addition to their standard install kit that's already listed 2010+ so now I'm not sure what it could be.
