Dont know if anybody is interested but I just found out from the factory that my 07 Wrangler X Came with a Next Gen D44 HD Rear end. Unfortunatly it still came with the standard 3.21 Gears. Does anybody know why they class this as a HD differential? Just curious

What you actually have there is the Standard D44. If yours would've had a 12 bolt cover then it would've been interesting as we are still kind of trying to determine when/where Jeep is using the 12 bolt Titan housing.

That's a good axle you have there. 32 spline shafts and bigger tubes than the D44 in the TJ's.
