I have searching and have come up with some conflicting posts on the spline counts between the 242 and the 242hd. I know the "HD" TC comes out of the 02-03 GC with select-trac and everyone says it is HD because it has 32 spline count on the output shaft while the 99-01 V8 242 only has 27 splines. Also there is a tail cover for the 02-03's instead of a boot, is this correct? This leads me to my question: my 2000 242 transfer case has a 32 spline count along with the tail cover and not the boot, so are there some exceptions of the "HD" transfer case in earlier models? It could be kind of like how there were very few models in 2001 with H.O. engine that really most people didn't know about. :dunno:

What you describe (32 spline output with alum. tail cone covering the splined section) is in fact a 242 HD. Why on a 2000 (it says 2001 on your drop down menue BTW, may be you have a 2000 too? IDK) I'm not sure, but prolly a few V8s then were fitted with a 242?, or the previous owner swapped it out?

Someone or a dealer swapped the HD t-case into your jeep.

Do you have a picture of it?
Either they're wrong, or they did take it out a 2000, but someone had swapped the HD into that Jeep.
As you mentioned with the HO engine in a 2001, there were a couple HDs in 2001, but I doubt as early as 2000.

Well, if its a 242HD, then all the better right? I had ordered a new rear drive shaft for from a 2000 model V8 242 and it had incorrect spline which got me questioning everything. I guess that means I will just have to get a drive shaft from a 02-03

Yea sounds like you need the 02-03 DS.
All the better.

there was a grand for sale by me (PA) it was a 2001 they guy ordered it direct from the factory. he claimed that he had to all this special stuff to get them to give him a 242 (HD?) with the 4.7HO. he did a custom order i almost bought it but i had just got my overland. so maybe this is a special order like that one?

In the part manual for year 2000 it shows what appears to be the "HD" transfer case. The part # on the case is the same one that shows up for the V8 option (EVO code, 6 cylinder is ERO) and there are only 2 cases; one for the inline 6 and one for the V8. I would assume that there would be 2 cases for the V8 cause most people have have the one with the boot covering the output of the driveshaft. Here are some pics from the 2000 part manual

I'm going to clarify about this, ALL v8's bring 242HD, since 2000 to 2004; the only exception is the 242 from the 99 .
In the other hand, what is described by you apply to the I6, in another words, from 99 to 2001 the tail is a rubber and starting 2002 all of them are the HD's.
There was a misinformation that the people repeat, repeat and repeat all the time. The same with the viscous coupler in the 247's, there is a viscous coupler in the 247 and a gerotor pump, both work together.
Hope this help.

Thanks for the response and clearing things up this is what I suspected after getting my transfer case in and reading the parts manual for the 2000 and up grands. Where did you find this info? Did you use the part manual too? Sounds like the thread in the sticky section on 242 swaps should be updated correct?

Nope, I was seeing those parts in the junk yards, and I learn from the field and some sites.

I guess nierace started the rumor that the HD is only in '02-'03 V8's http://www.jeepforum.com/forum/f13/jeep-wj-247-242hd-swap-510546/

A viscous coupling in a 247? Really? Do you know what a viscous coupling IS?I'm going to clarify about this, ALL v8's bring 242HD, since 2000 to 2004; the only exception is the 242 from the 99 .

I disregard everything else you have to say by that statement alone.
You could probably have special ordered a 242hd as they were standard equipment for durangos.
