Thanks I had no idea you could do that.MTH said:As I understand it, all JKs have D44 rears except for a handful of 2007s. So yep, you've got a D44 rear.
You can register your jeep at jeep.com and get a print out of your build sheet, which would confirm it.
Yup, look at Pluke's pics. That's a D30 front and D44 rear spinning 37s. I assume that just about covers what most folks are looking for in terms of durability. In terms of spending money on upgrades, JKs can often use new gears, new ball joints, and maybe c-gussets, but new axles usually aren't on the short list.But Dana 44s are still good right? I've heard good things about them
Ahhhhh! Forgot about those important items. Thanks.Axle shafts and u joints are smaller on a 30. You're getting a lot more strength all around with a 44. The tubes and c's are the same weak points on the 44 as the 30.
