Now can you hear this noise when you back-up or go forward and will it occur under a load or no-load condition, engine torque? If you have a two piece drive shaft could it be the u-joints instead of a carrier bearing? I would also craw under the truck and see if there is any slop or play in the u-joint/carrier bearing.
I know that several Ram trucks have been changed out to the one piece drive shaft from the Mega Cabs to eliminate the carrier bearing on their trucks.

Yea It has a carrier bearing. I can only hear it going forward not backing up.
I step on the gas get it up to over 5mph then let off gas and you can hear it.
I took it to the shop and a guy took it for a test ride and could hear it too.
He thinks it a rear axle bearing
The truck only has around 55,000 on it.
Well have to take it back in mon when they are more guys on staff to get to it.
How hard is it to replace the carrier bearing ?
