As anyone swapped a rear driveshaft out of another vehicle to put in their xj?

With an SYE you can swap an XJ front driveshaft i'm for a rear (you'd be running an two fronts) our if your lifted 6"+ a ZJ driveshaft (not sure if front our rear) but i'm not sure about a different vehicle, what did you have in mind?

Its a 4.5" lift but measures to 6.5" my rear shaft wanted to come out driving around town

Do you have a slip yolk eliminator? If so i'm running 2 XJ fronts on 3" right now, it feels stock again haha

No sye...i hear zj front and rear driveshafts work, is this true

make sure your spline count is the same on the output shaft for your slip yoke as the zj rear

Could i just swap the yokes? Is a zj shaft longer than xj shafts?

If you still have the stock driveshaft you will need an SYE to swap to either the XJ or ZJ Shaft, your out put shaft on your tcase will look like this when finished

I know what it looks like but are zj shafts longer that xj shafts

If you have such an extreme driveshaft angle that your yoke is slipping out then you NEED a slip yoke eliminator. As your rear suspension compresses it will push up on your driveshaft instead of pushing in as it is originally designed. You will end up bending output shafts, breaking tail cones, and tearing transfercase mounts. Especially if you do any sort of high speed stuff. Believe me, I have had problems with every single one of those.

Spend the 160 on ebay for a rugged ridge sye and mainshaft replacement. It will be worth your while. Run a stock xj front shaft in the rear like already stated or source another shaft from this list that might help.
