I have an 03 dodge 2500 cummins and it keeps pushing the carrier bearing out of the rubber and the bearing pops out and wrecks the rubber in the process. it always pushes out the front never to the rear. It has wrecked about 6 bearings in 3 months. the truck has 2'' rear lift blocks that were installed before I bought it. Im guessing it has something to do with axle wrap but I don't know how to solve it. I have friends running 37 in mud tires and much larger lift kits and have had no issues whatsoever with identical pickups. leaf springs shot? letting the axle wrap too far and pushing the bearing out?

 

I have 04.5 dodge cummins longbed 6" lift with the same problem, already went through 3 carrier bearings all of them pushing out the front towards the tranny. I have not tried the solid rubber bearing yet, the only fix im aware of is to get a single piece driveshaft. keep me posted if you find a fix.

 

Do you have a lift kit? Bigger tires? Sounds like you have excessive axle wrap. Maybe a set of traction bars would solve this issue?!
