I am getting ready to replace the drive shaft center support bearing and carrier on my 2005 3500 diesel dually. However there seems to be two sizes available, 1.378 dia and 1.575 dia. How can I tell which one I need without taking it apart and then hoping I can get the correct one locally.
I'm not sure how I figured mine out but mine was the bigger one. Also after the 3rd time swapping it out within 60K, I ended up getting a single piece driveshaft.
