ryanmcfarlin it could be the cv driveshaft part it did look like it was bad and when i replace the yoke i get a real bad squeaking sound but when it is insatlled it looks like the picture. so i will replace the knuckle part and the end yoke and see it that works

JeepAddOns-Chris My guess is that with that much of a lift your driveline angles are way off. Your driveshaft should be pointing 2-3 degrees below the yoke on your transfer case when the Jeep is at rest. If your driveshaft is actually going into your transfer case, that is a stock style driveshaft without a SYE. This is stock.



With an SYE and double carden (CV) driveshaft



If it's truly a SYE and your angles are fine then it could be that the yoke on the SYE is bad and needed to be replaced. If it's what I think it is and the angles are off, then you can use degree shims in the rear to get your pinion angle correct.

Redrider94 How far does the yoke go into the transfer case? Could be that you are not going in as far as you should, meaning the driveshaft would need to be longer. Post a pic of the broken yoke, we should be able to see how much is in the transfer case.

sevenservices are you running a slip yoke eliminator? transfer case drop?

I would be interested in a pic of the angle as well...

89Saharagreen When is it breaking from your post it sounds like it has broken more than once or twice have you isolated when it breakes I.E. driving 55mph down the highway vs rock climbing?

Also how much lift are we talking about and which driveshaft I am assuming the rear but you did not say or if you did I missed it.

Lastly what kind of drive shaft is it a custom one or original?

Pics can also help.

Just my .02 cents.

JeepAddOns-Chris What kind of lift and what size? If stretched, axle wrap can cause it to break. If it's lifted too high and angles aren't addressed can cause it to break as well. There are other reasons, but those are the two most common.
