Carrier bearing drop kit. Do I need one?

I recently lifted the rear end of my 2015 crewmax with deavers 2" rise springs and camburgs 1.5" shackles and three days later my carrier bearing went out wondering if it was do to new angle and if a drop kit would of saved my bearing..

 

Hi everyone I have a 2/1 leveling kit and have a 5/8 spacer carrier bearing drop kit. My working angle on the front middle and rear 0.6- 0.8- 1.7 degrees. Are those good numbers or do I need to go bigger on the spacer? Don’t notice any vibration.

 

Common thickness for the carrier bearing spacer is 3/4 inch for a 0-2 inch lift.

 

Yeah I figured it was around there. I just got some spacers at ace hardware.
