My '05 dually has a 3.73 LS with disc. It is a 4WD truck. What year ranges are inter-changeable? I found an '02 dually 3.73 LS with drum, can I swap my disc brakes onto that? What is the difference? My axle tube has separated from the pumpkin housing. I have been told my 2 differential shops that it cannot be welded. They told me to replace it. These things are very spendy! LOL I am sure many of you know that.

I'm not sure about brake interchangeability, but all rears behind Dmax's should be AAM 1150's. Don't know if the axle design itself changed at some point. I would think not...other than the switch to discs.
