Seems you can turn a TJ into AWD with 4:1 low range

happen to know that a adapter plate is made for back of 5speed to fit a Rover Tcase.
Rover Tcase is very very adaptable according to Colt Builds it. Various low and high range rations available AND AWD planetary available.
Rover Tcase made to go behind V8, so plenty strong for TJ/LJ

Buttttt. you have to swap to passenger side pumpkin axle also. (cherokee front axle?) (unless you can flip the rover tcase?? ).

Why not use a NP-242 transfer case used in XJ and ZJ ? It can be used as full time , part time and has low range. No sense adding limey nonsense to the mix.
 
I can’t imagine a scenario where AWD would be more desirable than part-time 4WD in a wrangler, besides pavement.

And you would have to reroute almost the entire exhaust and figure out front axle linkages for the axle housing.

Snowy paved roads or sand.

no other low ranges available.

No other division in AWD between front to back beside 49/51 (think that is the split) Id rather something closer 40 / 60? 30/70? Not clear what options in split power front to rear the AWD Rover Aftermarket sells though

4wd works great in snow and sand. You only need awd for dry pavement and sharp corners.

EXACTLY.

just learned about Rover option lately. Am installing NP242 cause nearly got that ready to go in all ready.

Why @Tob AWD? Got Diesel engine in TJ (once old diesel is out and my new one is running and got TJ on road again). MY scrappy old diesel in it before...... on wet roads; even after rain stops, Torque caused backend want to swing out. Good ol' diesel torque.

Have spun and nearly died with a stock TJ engine from black ice decades back... would like to avoid that potential again.

makes lot of sense... but rover option was not a known to me at the time. Thus was/am installng NP242. Maybe few years down the road could switch to Rover cause well..... there is two in my back yard and one has the adapter plate that would be needed to fit the 5speed Jeep

Had a scrappy diesel transplant in TJ very short while ago. On wet roads it swings my back end all over the place... hence why wanting AWD option cause when all said in done..... will have snow to contend with too. Upgrading from scrappy dieing old diesel to new one with upgraded IP as we speak so torque is going up more. (OM617)

I partially agree, 4WD does work great in sand and heavier snow in many situations. In the part of OH I live in, we get enough snow to need extra traction, but not enough where its slick all the time. Last winter I was driving around, and it was slippery enough to be sketchy in 2WD, but too many dry patches to keep in 4WD.

When I am in the sand, I prefer 2WD so I can go faster than I should. I only use 4WD when going up some hills without a run-up, but even then I can go all around Silver Lake in 2WD with gunning it. 4WD just feels like it binds and robs power when bashing through dunes.

I think there is some good middle ground in both snowy and sandy situations where AWD would be beneficial, but it will never fully replace a proper locked 4WD for the more difficult terrain.

I'm not seeing any reason why I would want 4:1 and awd at the same time.

Possibly a case with awd/hi and 4:1/lo part time.

Front and possibly rear axles with wrong offset.This just isn't juice worth the squeeze

Yeah there are places that regularly get dry pavement with patches of snow, and awd is better for that. But 4hi does pretty darn well, too. It's happy going 80 down the interstate, and only objectionably binds up on sharp corners: right hand turns at intersections, parking, etc. Even then it isn't a big deal. Like having spool on the rear axle. Yeah it'll chirp on sharp corners but other than a little tire wear it won't hurt anything.

People tend to think that 4x4s are little bitches that will self-destruct if used on pavement. If it can't handle turning on pavement it won't handle crawling on rocks. If you have a mall crawler running 38s on stock axles, yeah you risk breaking shit on flat pavement.

I don't thing awd would be any better on sand. 2wd keeps the revs up by letting the tires (or a tire) spin.

I am putting a 242J while doing the LV1 swap in my LJ so I am curious to see how the AWD will do in the sand compared to 2 or 4WD. But the LJ is my versatile adventure rig that will see all sorts of terrain and weather conditions both paved and unpaved roads so I decided it would be nice to have that option especially since I got 2 XJ 242J for free.

My main sand rig LS TJ may end up with the other 242J I have lying around, but it has enough power it probably wont make any difference between 2WD and AWD.
 
Sounds like an issue of driving style and/or poor tire condition.

nah, likely more of an exaggeration on my part on unplanned rear steer of back end.... and your taking the exaggeration further than I wrote.


Short wheel base will always easier want to rear steer you if that is the only place your power touches the ground. Just matters friction (or lack of) and torque. Just how mother nature of Physics works.

we are not far apart in distance. I forget there is like one place in all of OH with sand (if memory serves me right).. never been there. Granted not been wheeling in decades*. This diesel TJ is suppose to be my foray back into it sorta. Main intent is for it to be daily driver/weekend explore along with partner in crime as the toad (towed) behind Expedition Camper am (way way) to slowly building (LMTV based)

As to AWD and sand...... will be hard to compare due to wide variables. AWD so widely varies. As in it matters what the AWD start point of power to the ground is before the center differential-ish action starts moving more power to slipping front or rear axle. Example appears the 242 is 51/49 range..... rear /front? as the power division in AWD. Where in my LMTV it is 70/30 .

And of course sand varies wildly.... from fesh fesh baby powder to Sand Hollow in Utah to Sand Hills in northern-ish OH.

*at one time had wheeled enough to end up journalist for now defunct 4wd E-magazine as it was called back then.

There are ORV sand areas in OH? I don't know of a lot of places to really take ORVs to here except a few forest trails in Southern OH. I go to Silver Lake in MI quite often, enough that I am looking for a small property around the area to put a cabin on and a shipping container for a garage on. Also Badlands in Attica IN looks like a fun place to go to as well that has sandy trails.

Badlands in Attica may be what am remembering and just mixed it into OH by mistake?? Seem to vaguely remember something Sand-ish.. but long ago wheeled in many states soo it all gets jumbled up in my head. Quick search for [ "Sand" offroad "Ohio"] seemed to show some promising leads though

who said anything about low range in AWD? Of course would only use such when using 4wd option.

far as I know zero issue with driveshaft line toward rear. Certainly something to look into though. Will look. Granted myself am in position to really cheat... If the rover axles are any good at all.. I got pair of front and rears outside in vehicles.

Northeast Ohio has a spot called Southington Offroad, near Garretsville, OH. AKA Southington Hunt Club, it's a quarry that has a Jeep/Fullsize Truck event once every other month now. Used to be first weekend of the month, but now hosts ATV'S SXS alternate months.

There are a couple of areas that have sand, also pea gravel. Also has rocks and mud. Not real big, but only 60 miles from home, so I usually get there once a year. I tend to go when drier in the summer, avoiding the wet and muddy seasons.
