How easy is it to break an axel?

So I have an 04 Jeep wrangler sport and I'm planning on putting 31 inch mud tires on it. Does that add extra stress on the the axels. I don't know what ones I have, it's what ever it came with and I believe it's danna 35. Also is there any tips for not breaking my axles? I have been watching some YouTube videos and I have seen some axels break really easy. Is there any tips for not breaking my axels on the trails.

31s will be fine with stock axles. most people who break an axle, have big tires, lockers, or are far too lead footed when they get stuck.

Know that the d35 is probably the biggest worry on Jeep forums...so there is lots of hype that they are junk. While they might be a weak point, most of us don't put our d35 in the hopping bind that typically causes them to break.

If you watch youtube videos...they all seem to have something in common...bounce, twist n snap.

even then they will generally hold alright with smaller tires. getting to 32s and bigger you can start to worry, but unless you have the extra money, and have other important things like a winch done I wouldn't upgrade or replace my 35 if I were running it open with 31s.

For the most part, the Dana 35 rear axle holds up. The Dana 35 is fine for casual offroading with 33" and smaller tires so long as you aren't being a wild-man on the trail and also don't install a locker into it. A locker can double the torque/load/stress placed on an individual axle shaft which is how most of them are broken. I dunno the percentage of Wranglers that have the Dana 35 rear axle but it's probably at least 90% so it's not that bad of an axle... for casual offroad needs.

It's when you start doing more difficult trails, going with big tires, lockers, etc. when the Dana 35 becomes a problem. That said, I have personally had to help Jeepers get off the trail with broken Dana 35 axle shafts with 31-32" tires and no locker so if you're too aggressive, a busted axle shaft can be the result.

The good news is even a broken axle shaft does not have to be catastrophic, they are easily & inexpensively repaired... it's not like you have to replace the entire axle so don't worry about the possibility too much... a broken Dana 35 is not as likely as some make it out to be.

The front Dana 30 is much more reliable in that it seldom sees more than around 50% of the stress that the rear axle does. People commonly run 35" tires on the front Dana 30 with the occasional need for stronger aftermarket replacement axle shafts once a locker is added.

All in all, a stock Wrangler TJ is very worth of being wheeled right out of the factory and it doesn't need any upgrades to make it reliable. It's just when the newness wears off and you start seeing and trying more challenging trails when it's time to start evaluating your true offroad goals & just how much abuse you want your TJ to be able to handle without worry. Then the sky's the limit on all kinds of fun manly-man upgrades you can do to it.

look at the housing, the shape is one way also the fill plug being rubber vs metal. there are many threads on this.

I can't post pics right now but basically...

Dana 35c: It has a perfectly oval-shaped differential cover on its rear with a black plastic snap-in plug for the cover's lubricant fill hole.

Dana 44: It has an angular almost stop-sign shaped differential cover on its rear with a threaded steel plug in its diff cover for its lubricant fill hole.

Almost every video I see of an axle breaking it is because the driver always is mashing on the accelerator with a bunch of wheel spin, and then something suddenly catches. Rocket science I tell you. Another reason of the importance of proper gearing.

I believe all "x's" came with the Dana 35. Like posted above the fill plug and shape is the way you tell.

Definitely always a Dana 30. Only the Rubicon has anything else up front and it has a Dana 44 front and rear.

As far as I know the X never had the option to have a D44. And that the X was just the base SE model with the 4.0

Incidentally... the '97 TJ I bought new originally came with a Dana 35 and 13-14 years ago I installed a lunchbox locker into it. I knew it was risky but I thought I might be ok if I was extra careful with it.

I took it on one offroad trip 2 weeks later and was so gentle on it that those behind me were bitching on the CB radio for me to speed up. It survived. Then 3 weeks later, I was making a very gentle slow u-turn at an intersection in downtown San Diego. The differential itself grenaded with a noise loud enough that I saw pedestrians 2 blocks away instantly look my direction. It was so loud that it scared the crap out of me.

I had literally been EXTRA gentle on it with 33" tires. Of course not all will self-destruct as easily as that but it just goes to show you how risky adding a locker & bigger tires to a stock Dana 35 rear axle can be.

if you want to keep your 35 and put a locker in put chromoly shafts in it. they're pricy but cheaper than a d44. not as strong as a good d44 but better than a stock 35. the 35 is a good axle for the majority of anyone who will be using it. but if you want a locker, upgrade.

Im not adding any lockers, just some 31 inch tires

you will be just fine with your 35. im running 32s on mine and wheel the hello out of it. just make sure you change the oil in it once in a while and you've got nothing to worry about.

Everyone always dogs the Dana 35 but honestly on the VERY long list of parts I've broke on many jeeps, personally I have never broke an axle. And Iv had 4 jeeps with 33s or bigger and a dana 35. some of them with lockers and even welded. And they all have been far from babied. But also I understand the 35 is weaker compared to other axles. As iv done 3 8.8 swaps in my own jeeps. But I do believe it is a little tougher than ppl give it credit. But that's just my opinion.
