It makes a lot of sense. I appreciate the advice everyone. I guess I have to start using that nice new winch on the front a little more!

 

I'd be up for it.

 

I am going through the same thing did some research jks are not supposed to be lifted 3+" without upgrading the drive shafts to allow for more angle jp magazine has a small write up on this problem it is not specific to which lift kit you have it is specific to being lifted period the jk has a fixed yoke unlike the TJ no one knows what jeep was thinking when they designed it this way but now you have to up grade your drive shaft with a universal style joint. at this time i am trying to get the dealer to pay for the upgrade since it is not operating up to jeep specifications they installed the lift they said it is covered under manufacturers warrantee. read the write up

From my experiance.. If your bending them and not braking them.. Then you Axle tube is bent.. I have experiance the same with both my past TJ and my Rock Crawling buggy...

 

If the axle tube is bent, does that mean I not a whole new axle?

Thanks.

 

This thread is about breaking axle shafts, not driveshafts. Further, no where does it say that you HAVE to do the driveshaft upgrade. Here's a quote from one of the articles: "While we didn't notice any binding or problems during our trail testing, time will tell whether they will hold up long-term." So far, there haven't been many (if any) reports of driveshaft breakage. I have seen 1 picture of a torn/destroyed driveshaft C/V boot. I believe this was on a 4" lifted JK. I'm not saying it's not a good idea to replace them, just that you don't HAVE to replace them. The angle on the front shaft at the T-case end seems to be the worst.

 

when you say bumping an obstruction is going to be different than boucing off the same thing think of a good tall curb if you are not able to just go up it with ease you back up a little bit to try it with a "LITTLE" more speed couple mph not 10 -20 save that wheel speed for sand hills

 

Do you have pictures of the broken axle shaft?

 

the stock rubi rear shafts are plenty strong for 35's even if you use the skinny pedal

me thinks there might be an issue with the axle

do you have bind??

lots of issues could be at hand here

1. bind in the driveline
2. if you had gears installed, a bad gear install could theoretically cause an axleshaft failure
3. check your axle tubes for stress cracks or visible distorion (meaning if its bent)


id be interested to see some pics of the rear axle and the axle shaft breakage as well
