Front drive shaft
#6
JK Super Freak
I have a 11 and swapped the DS with something earlier. Dropped the shaft out and kept the yokes in. 12 bolts and good to go. You may wanna get a small 1/4" socket to get in close to the bolts. It's an hours or 2 at most. Not hard at all

The drive shafts for the 2012-2013 JKs are different lengths than the 2007-2011 because of the different drivetrain (engine and transmission). I'm not saying they aren't interchangeable, but I'd double check the lengths and clearances to be sure.
