transfercase swap questions

I'm sure this has been brought up before but I was not able find the answers through the search.

keep in mind I am a newbie and may be off of my terms etc.

First off my jeep is a 94 yj 2.5L. (stock height, no lift)

Recently I cracked my transfer-case housing.

I do have another, however I believe it is out of a 98 TJ 2.5.

The difference that I am worried about is the rear shaft/cone. The old one has the full cone, the new one has a short cone and rubber boot and is 1.5 inches longer.

if I change to the new transfer-case can I use my old driveshaft?

if not would the easiest remedy be to use a drive-shaft out of a 98 TJ? or would I have to get my drive-shaft shortened and balanced?

Thanks for the help!!

Assuming all parts are stock on your 94, you may be able to swap the slip yoke (cone) assembly off your 94 to the new TJ case and keep your old shaft. By the sound of it, your 98 transfer case has an aftermarket slip yoke eliminator (short cone) on it and they come in many different sizes (lengths) so a stock 98 shaft probably will not work, you'd have to have your shaft lengthened (not shortened) and balanced, or have a new shaft manufactured for your new configuration. You probably have a local custom driveline shop or you can contact Tom Woods driveshafts and they can walk you through it, they're great over there.

There is no SYE kit, just on the new case the cone is shorter however the shaft is longer. (the pic in OP the new one has the rubber boot).

on the TJ that this transfercase is out of (if stock) would it have a shorter rear driveshaft than my stock yj?

Take a close look at both. Is your old tail one still good??? If so will it swap over??

What is the difference in length between the two?

I would try the driveshaft from the TJ same u- joints

I have never experienced this but sounds like it will work
