New member, new Sport/w questions on axles

I am a total newbie to the jeep JK and to this forum. My girlfriend who lives with me up on this mountain just purchased a 2014 unlimited sport. She needed the comfort and security for climbing our 3 mile driveway which is a rough one! (Understated) I am still at the stage of RTFM and have a question for anyone that has a much better understanding of JK mechanics. I was looking at the build sheet, and this Sport came with Dana 44's front and rear. It also does not have any locking feature on it. Can someone tell me the significance of ordering d44s on this Sport?? I have a limited knowledge of axles, quite frankly, and would like to know why the original order came with these d44's?? Are 2014 danas considered newer generation with beefier components or not? I am asking, "what do we have here"??







asking,

The D44s on a sport are heaver duty than the D35s that some come with. For the most part lockers only ship on Rubicon's. All Rubicon's have locking D44s.

Bottom line is that your sport has great axles under it.

All JKs now come with the new generation Dana 44 rear axle. A few 2007 JKs came with a Dana 35, but that was rectified part way through the model year. If you have a sport, your front axle is a Dana 30, not a 44. Only the Rubicons come with a front 44, and only with a locker. Your axles are plenty stout for stock tires, and even up to 35" tires. These Jeeps have a brake based traction control that will actually function as somewhat of a limited slip. When it feels a tire spinning freely it will pulse that brake which sends power to the other tire on the same a le which has grip. While no replacement for a true locker, I've been impressed with what that stock system is capable of. Unless you're going to a larger tire and doing some harder offroading, the brake based setup will likely be more than adequate for your long driveway.
