    Default Jeep JK Dana 30

    Not sure this is where I should post, if not, I apologize. I switched out my Dana 30 front axle w/ 4.10 gear ratio for a G2 D44 front axle. It’s an ‘07 w/ 100k miles. My questions is, is there any value in a D30 axle w/ 4.10 ratio (axle, gears, axle shafts) or should I just leave it behind? Thanks for any input!

    Can't hurt to post it up on FB Marketplace and CL for a few bucks. Better than scrap prices at least!

    I got $50 for my Dana 35 TJ rear axle way back when I swapped it out. Just found someone who only drove his Jeep on the road and needed a rear end.

    She may not look like much, but she's got it where it counts, kid. I've made a lot of special modifications myself.

    Thumbs up

    Lots of value!
    As a JK owner would than just have to find a Rubicon rear axle assembly or re-gear theirs 8)
    Traction, articulation, and gearing make a good off-road rig. Just a big lift, wide mud tires, and a winch simply do not.

    If you DO want to sell it, this section is a fine place for your thread as you should get interest. As stated, this axle definitely has value, the Dana 30 is a great axle but can become weak with tires 35"+ depending on how you off-road. A light foot on 35's can still run a Dana30 without much issue. Its when you start doing more hardcore off-roading that the shafts or joints are apt to break, tubes can bend, axle C's bending cause premature ball joint failure, etc... Having a complete Dana30 with 4.10's should not be a difficult sell and has much more value than a weak Dana 35 rear end.

    This JK axle assembly is a high pinion(the TJ model before had a weaker low pinion design) and has bigger bearings and pinion over it's predecessor, making it a stronger choice. Shafts can be upgraded, as well as ball joints. The inner knuckles can be gusseted and the tubes themselves van be sleeved. So don't let Anthony scare members away from buying it. A complete axle is worth something, especially to someone who wants a much better 4.10 gear ratio over the all too common 3.21, as it could save someone $500-$1000(depending on the shop) in regearing that one end alone ;)

    I don't disagree, hence why I said there is value. My apologies for not elaborating on all the methods of strengthening the axle, but yes these can all be done and will make it much stronger, at a cost. I currently still have a HP Dana30 in my YJ on 35s with lockers and 4.10 gears, I am not one to tell people to run from a Dana30 like many others. So yes, please don't let me scare anyone away from this axle.
