Using XJ front shaft for SYE

For those of you that cut down an XJ front drive shaft to use in the rear with a SYE, what method do you use to attach the DC end of the shaft to the yoke of the SYE? The shaft I got from an early 90's XJ has threaded Yoke type fitting at the DC joint. The JB SYE yoke has smooth holes for use with U bolt style Ujoint connections.

Will the bolts for the XJ work?

I used bolts to run through the SYE and bolt directly into the driveshaft.

It's supposed to be installed from front to back. Slides through the SYE yoke and threads into the driveshaft yoke.

I'm trying to figure out your driveshaft, it sounds a little different than my set up. I'm running a Rugged Ridge SYE, using a front driveshaft out of a '95 Grand Cherokee, and it simply bolts into the SYE output using the standard U-joint collars.

Just pick up some grade 8 stuff at your local Lowes or Home Depot.

I couldn't source any locally with the small heads so I got a set sent out from Summit. I left the ones I removed from he donor XJ on the ground at the JY

I have a bunch in the garage. I snag a couple from the pick and pull everytime I make a driveshaft. This way if I round off one or lose 1 I have extras. Grab a couple spares next time you go to the junkyard.

I will keep my eye out next time for shure! The JY I went to only had one XJ and the bolts were nowhere to be found. the other one in town won't let me wonder around so I dont normaly go there. But I will give them a try.

The front driveshafts (as well as the rear) use two collars on each joint, with 4x 5/16 (or 8mm) bolts. Depending on how the joint is positioned, you will probably need a a socket on a ratchet and a combination wrench. I like to take a full boxed end wrench, makes it a lot easier to remove the ones you can't get to with the ratchet. Plus, some are a little stubborn, so you need all the engagement surface you can get.

don't re-use the stock bolts, go to the hardware store and get some grade 8 5/16s fine thread bolts that r the appropriate length. If i remember correctly they were 1 1/4 inch long when I bought mine. Also using these will allow u to use a 1/2 inch wrench to tighten them instead of a socket with the other type. While ur at it get a little lock washer for each one so u can tell if they r tight or loose, I use blue(medium strength) locktite on them too.
