Okay, well I can speak with certainty that my front DS, fits in the back too. I've swapped them both out front to rear and vice versa, because I was trying to fix vibrations. The tom woods shaft is slightly shorter than the rear shaft, but they both work. (Tom woods is now in back, jeep shaft is in front. The TW is shorter, but does fit with no issues.
The "HD" refers to two things.
1) A non hack n tap flange on the transfer case... a Bolt on yoke that fits onto a heavy duty, shorter main tcase shaft.
2) A heavy duty drive shaft. The stock xj shaft has maybe 3 inches of splines, and a small machined shaft sliding assembly. The tom woods shaft has full length splines, and an overall thicker construction.
cool see even an old fart like me learns something new...i guess never had the issue with my shafts till after i was on 38's...i went from stock to 33's to 38's in about 3 mnths.. but i can still guarantee you will make it out of the woods in front wheel drive only long before you will in rear wheel drive only...i have tested this many times(in muddy nasty conditions only never in dry rocky terrain...
my experience in the past has been that the input shaft on the 231 is different than the 242 so my only experience with the 242s has been to rob and cannibalize bits and pieces in order to get back on the trails...just never seen a hd version...now im wondering if i can steal the pieces from an hd 242 case to upgrade a 231 for cheap...i just don't believe in too much bolt on...its an ego thing...no not really its a money thing...lol...thanks for not calling me a total DA...lol...
Be carefull while Hugging the Trees...They leave dents on your Jeep....
Shhhhhh I'm not crazy...It's just the voices in my head
.... the "np231-242-j" or which ever version you have(jeep cases) only come with 3 out of the available 6 planetary gears...the factory gear carrier cannot be modified, but if you go to the junkyard and get a "np31-242-c" full-size Chevy case(case bolt pattern not compatible) you can swap out the planetary gear assembly for the 6 gear setup...
VERY interesting!!! You've just given me something more to research.
I dont suppose you have a write-up of this do you?

So I mentioned that my friend Dillon got me a Yakima Loadwarrior rack. It was worth the 40 bucks, but it needs major work.
When he found the rack, it had a surfboard mount on it... so I imagine this thing had tons of salt water leaking down onto it.
Two spots are really bad... One of the crossbars is rusted through. I might just ignore it, stop the rust and put a metal screen floor on the rack.
I want to mount back up lights, an LED light bar, and some shovel/axe mounts on it. So it will be great when finished, but it will need some work.
And a shot of the mounting- The plates are from a Thule roof box system. My dad bought spares for his Thule a while back and these were just sitting in the garage. Cost- $0.
The rack actually "hangs" from the roof rails. But this also makes it impossible to remove without removing the roof rail from the roof = security. Untitled by Sean Mitchell 707, on Flickr Untitled by Sean Mitchell 707, on Flickr
This also makes it mount about 3 inches lower than normal. Way better!
Oops sorry for the double post. My phone's being janky
No worries. That is just the 2.5 inch pipe and the "baffled" muffler. I opted not to go with anything more expensive because that thing is basically a skid plate. Scratches and scrapes along the whole muffler.
It sounds good but because of my extended shackles, gas tank skid, and the big pipe, it was a pain to make fit, so I ended up cutting the turn down off, so it exits right before the bumper.
So because my radiator died on me back in like 2011... I had to do an emergency replacement at my old house in San Mateo. My dad and I literally did the swap in our empty house which had a for sale sign on the front lawn. 39c8ae4a by Sean Mitchell 707, on Flickr
Well, my ZJ transmission cooler had to be just hung up with a clothes hanger. I didn't have anything else. Ghetto.- 7389d237 by Sean Mitchell 707, on Flickr
I never got around to fixing it. So while I'm waiting to buy my detoit and allow shafts for the rear axle, I took the time to fix this right.
Those little straps from Hayden were like 8 bucks... so I decided it was time to upgrade. 45 bucks got me this-

And since my old cooler was right behind the winch, now was the time to make it more efficient. Untitled by Sean Mitchell 707, on Flickr
I had to remove-
-The solenoid box from the winch
-The winch from the bumper
-The headlight surrounds, and the grill
-The old cooler
-The e fan
The new cooler fits perfectly in front of the e fan. You can see the four plastic straps which go through the condenser, and radiator. Little foam pads between the cooler and condenser space it and make it so they don't rub.
And in other news-
Got my ring and pinion last monday. Went to take the damn thing apart- The carrier is worn out. The soupy metallic gear oil must have ground the wear surfaces down, the spider gears can be clunked up and down, and the cross shaft is loose inside the carrier. You can actually see where the hole in the carrier is beginning to mushroom out from the wear.
Also, the whole thing got so hot that the ends of the axles are burnished blue. Yikes.
I got it towed home. Couldn't keep it at work any longer.
