what transfer case

Could anyone tell me what 242 would be the easiest swap to my 95 v8, meaning what years, xj, newer xj??? I'm pretty pressed for time and can't really experiment

You will have to swap input shafts. No way around it. I have a 95 v8 ZJ and I used a 242 from a 1990 XJ. I had to get an input shaft from a junkyard tcase since mine has the new gear cut the the 90 was the old gear cut.

That's no big deal, as long as its the only problem. Don't have the time to be fitting driveshafts and whatever else

Thanks, but a little too general for the moment.... I'm looking for someone who has done it with the easiest transition. Someone who can tell me "this one or that one is the easiest, and least work. Like I said, I'm working 7 twelve hour days a week, so there's no time for experiments, drive shaft hunting or cutting. Right now its my daily driver, and the 249 is on its way out.

mid 94 was when they changed gear cuts. you will want an internal slip yoke 242 if you dont want to mess with the rear driveshaft. IIRC most 242s before 1995 had the internal yoke. its easy to tell them apart

^external

^internal (the one you want)

If you get a 242 from an older XJ (pre-95?) you'll need to swap the input gear, tailshaft is same internal slip yoke.
The VIC gear switch on them is 2-contact, different to one on 249 case and it's not possible to swap them
cause they are different length and located in different locations.

If you get a 242 from a newer XJ, input gear and switch connectors are same, but for external slip yoke
you'd need a driveshaft from a ZJ with an ESY 242 case. Pretty hard to find.

Or just cut up your 242's output shaft to same length as 249 was and re-use the original tail shaft,
just add a rubber boot for splines from any ESY XJ tailshaft.
They're pretty much the same, ESY and ISY tailshafts, just different length.

Thanks, I could care less about the vic switch. Mine doesn't work anyway. That sounds like the way to go

I just put my Vic shift sensor in the 242 case to plug the hole, it will thread in, but it wont work right. I Just zip tied the extra plug up out of the way
