Do i have a Dana 44 on my jeep?

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.

Forget 07-08 but one or both had the option of a 44 I think.
Edit- ok guess Im wrong here

Zoom out. Lets see the whole diff

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.

That is a 30.

I looked at a 08 and it had a 30 as well

The front right?

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

The rear D44 is the best axle that jeep has put in the wrangler

Wait.. Yes

The rear would be a 35

Only a few 07's had 35's like MTH said,

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.

Are those stock jeep rims with a big tire?

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.

Oh no.,, who got Pluke going?

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.

So I took your advice and I registered my jeep and it says I have a Dana 44 hd rear and a Dana 30 front

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.
