I was getting ready to cut my output shaft after following iron rock's measurments. Going by there measurments i would have about an inch of splines left but the new yoke would be to long. the end of the new yoke would hit the tcase and leave a gap on the inside of about an inch between the end of the output shaft and were yoke should be bolted. Any ideas, am I doing something wrong

a couple more measurments. Refurbished double cardan CV driveshaft (Original equipment XJ or ZJ front driveshaft) 35 3/4 collapsed and 39 extended. measuring from the center of the ujoint cup on the pinon to the tcase seal is 36. I dont see how this will work. This would allow for extension but no room to collapse

most ppl end up cutting the new yoke down. i just cut the output shaft to fit the yoke. has worked perfectly ever since.

I have never seen their directions, but I would plan to cut so the output shaft splines match with the yolk splines (if that makes sense). Then measure from there and see what the DS will look like.

I guess after re-reading it sounds like there is too much material on the yolk? If so, I guess listen to xjcannon and cut down the yolk until you just have enough spline to match the output shaft.

Basically the same setup and yoke.

Trim the yoke length to fit the shortened T-case output shaft. I installed a 3103-27CV style yoke from IRO and a front XJ drive shaft on a buddies Cherokee and that's what we did. Works great, no problems.

Thanks for all your input. How much should the ds be able to collapse when just sitting level?
