Engine vibration..

I've got a 2010 with about 105k on the miles and just recently started this after I put the carrier bearing drop kit on it. I was thinking maybe it was my carrier bearing itself going out.

 

I dont think you have engine vibrations causing your issue if you did a carrier bearing drop and only after the carrier bearing drop you are now feeling vibes . Sounds like you changed your driveline angle and created a vibe by doing the drop .
