I have a 2008 unlimited Sahara and I was wondering if I had d44 on the rear. I'm pretty sure the front is a 30 but not to sure about that either. How do I find out?

These are the pics from my rear axle

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.

Thanks I had no idea you could do that.

Also this is the front
I'm thinking it's a 30
Yes indeed. Except for a few early 2007s, I believe all JKs have D30 fronts and D44 rears, except for Rubicons which have D44s front and rear.

But Dana 44s are still good right? I've heard good things about them

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.

i got a dana30, locked, re-geared, and on 37's no issues..........

dana30's are just as strong except for the ring and pinion which is a litte bit smaller.
Are those stock jeep rims on a big tire?

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. Of course relative to tire size, not talking about huge tires on a 44.

The longevity of a 30, on 37" tires has more to do with the driver, then the strength of the axle. 30s werent designed around 37" tires for sure.

In addition to the strength, you get the plus of running deeper gears without having to addl mods associated with the 30 to fit em.

Ahhhhh! Forgot about those important items. Thanks.

And I totally agree. The Dana44 is stronger overall.

But I am a firm believer in... if you break a dana30 axle chances are you probably break a dana44.

Good way to explain the variable of driver skill versus the actual integrity of axle strength. A lot of people break the 44 and a lot of people break the 30. But there also is a lot who do not break either one. And this comes down to knowing your limits and varying driving styles.
