XJ front DS as YJ front DS; TC yoke change??

If I'm using a front XJ DS as a front YJ DS do I have to change the yoke at the TC?

I have XJ front driveshaft as my front driveshaft. You need the front yoke off the XJ transfercase at the same time you get the driveshaft. It will have to be lengthened to fit.

Thanks a lot, yes I know I have to lengthened the XJ DS. I wasn't sure about the yoke. I have another question: A 1" shackle lift will throw the length of your OEM front DS off by 6"?

My shackle lift definitely called for a longer driveshaft but that was only because I'm already SOA with 2" springs. I would get your jeep sitting exactly where you want it and then make a custo measurement from ujoint center to ujoint center. This way you know you are spot on in length.

Oh and FYI, the XJ yoke and YJ yoke are interchangeable, just toss up the cv-style XJ yoke and you are good!

A TJ front drive shaft will work, you just need the CV style yoke off of basically any Jeep with a CV style front output yoke. Manual 4 cyl or automatic 4 or 6 cylare the same length, and the 6cy manuals are longer. So you would need to get one from a 97-02 with a with the same setup as your Jeep. Later drive shafts, I'm not really sure about, but I did just buy one from a 05 (not sure of engine or trans) and it works perfectly for my Manual 6cyl YJ.

That's what I thought but check the difference in size between the "black" DS and the other one. The "black" DS is the one "this" guy gave me. Supposedly this is the DS HE pulled from my Jeep. The other one is a DS from a bone yard (4Cyl manual).

They are fully closed

Can you get some actual measurements? Both driveshafts and actual length between yokes?

so your comparing a 2.5l front drive shaft to a 4.0l front drive shaft of coarse they are going to be different lengths

Hey I'm comparing nothing, my rig is a 94 Sahara 4.0 I6cyl. I took the Jeep to "this mechanic" to re-gear the front axle and replace the rear but HE dropped the job half way. He disconnected the front DS because of the ratio difference (front 3.73: rear 3.07) so he gave me the "black DS" when HE abandoned the job and I left. Now I'm putting the rear on the Jeep 3.73 but when the mechanic try to fit the DS it was @ 6" short, that's my point here. This "JERK" (Solofabworks.com) gave the wrong DS obviously. If you read carefully you can see that I got the DS from a bone yard and we fit/test it and is the correct length

The long DS is @ 40" long, the black is short @ 36" and I don't know from which vehicle HE took it.

I just swapped mY wrangler from a 4cyl auto to a 4.0 manual. The measurement I took from yoke to yoke was about 40 3/4". Fully extended, my 2.5 auto shaft was 41". I didn't take a measurement of the new front shaft, but it was substantially longer.

So, if it was swapped to a manual, it would explain the different shafts.

I just read a little more carefully and see that you got it figured out.

This is the measurement @ 40 3/4" of my rig (yoke to yoke). This is about right.
