What Driveshaft Do I Have?
 

I am trying to determine what rear driveshaft is in my wife's truck so that I can purchase the proper u-joints and carrier bearing.

2006 2500 Megacab 4X4 G56

2 piece rear driveshaft
Part #: 52123105AA
Subassembly #: 40036203
Serial #: 32850074A

I can't find this info anywhere. 1410, 1480, 1485, something else??? Really appreciate any help!!

Your local parts store should be able to determine this with the information you have.

Found the info I was looking for.

Contacted a few local dealers and they all gave me the same info. It would appear that I have the AAM 1485 2 piece driveshaft.

Driveshaft part#: 52123105AA

Carrier/Center bearing
MOPAR: 5183075AC
AAM: 40041712 which has been replaced by 40048725

U-Joint
MOPAR: 5102157AE
AAM: 74081485
Spicer: 5-3206X
Moog: 351A

Got the driveshaft out and found the slip yoke at the carrier bearing is damaged from the broken u-joint.

Slip Yoke
AAM: 40038564

Of course the dealer wanted some crazy stupid price so I went elsewhere. Had some coupons so got 3 Moog Premium u-joints for $81 total. Found the AAM bearing for $52 and the yoke for $68.
