ok, sounds like the way to go. i like being able to choose anyway, full time seems like it would put a lot of rare and tear on the jeep. so how would i know if the vc is locked up? is it something i can determine just from driving or is it a tear apart kinda deal? it will be a dd for now, then a toy later on. thanks for the input!

If the front drive shaft is laying in the back end, you'll know for sure.

When you drive it, you'll know something is wrong and it will feel like the wheels are binding up in the front. Revove the drive shaft and it will be fine.

I just bought a 93' and a 95' Grand Cherokee Limited 5.2 liter....each with 172, 000 miles and the 249 works fine in both.

Here's a 231 I just finished up for another member here. It was fully rebuilt along with a Rugged Ridge SYE, and a 1.55" input shaft:

Is that for a 4.0? The 249 inputs are around half that length. (on the 5.2 anyway)

Found a 231 today in a 95' Grand Cherokee 4.0 and immediately pulled it.

It appears, using my "digital eye scale", to be a .750" input which will swap right into my AW4/4.0 project.

Going to pull the 242 from a 96' Orvis edition on Wednesday.

Both for $200.

I have 3 running 249s, 2 good(both V8s with 170K)/1 bad(4.0).

EDIT: actually have to swap the inputs due to gearcut, my other Jeep is early 93'......... it was inevitable.

It was built specifically for a '95 5.2. The 46RH utilizes a 1.55" input.

The gear cut only matters if you HAVE to swap the inputs due to them being the wrong length or the wrong spline count.

So today I went and picked up the 231 I pulled from a 95' GC 4.0 yesterday for $79.50. It is .750 input which is what I need, but the manufacture date is January or June 1995.

Will this bolt right into my 93' AW4(.750 input), and fit correctly? If it will I just got a hell of a deal and a lucky-*** find.

EDIT: yes it will, thanks ZJFABN. I got lucky, will have to do more research before pulling cases for my V8s.

The gear cut ONLY matters if you are swapping the input shaft. You dont need to swap the input shaft if its the correct spline count and the correct length. Count the splines on the input shaft (the part that slides onto your transmission) It should be 23.

he has a 94 with the 5.2 = 46RH=1.55 input = an input swap for any 242/231

ok so i found a 242 for 136 bucks.
now i run a 249 with busted vc.
since vc is kinda expensive i go for this.
i have an 94 grand cherokee limited 5.2
not sure what year the 242 comes from but i have to check ONLY the shaft that goes to the tranny right??
should be 23 ????

also thinking of the shafts.
my front drive shaft has an 'extendable' part on it just befor e the diff.
does this matter etc??
and prob i will have to take that bezel to right?
since thats also 2wd i only have 4high and 4 low

also im gonna take the antenna and the left front blinkerlight

i have read the whole post and explains alot but just making sure incase i read something wrong

edit; in the door the plate says manufactured 93 but title says 94 and i just bought axles for the front all based on 94 so i think ill stick with 94 since that is everywhere except on my plate in the door.
