i like my 231 alot, it just sucks when im on a mountian road and theres big patches of snow and some dry road, it grinds alot, also, i have 33s and my front tires are way more worn out than the back so if i start to go over 15-20 mph it grinds alot because my tires are off size by about an inch

There is also the metal place underneath the shift bezel that locks the shifter in place. it's what makes you have to pull the handle to the side to continue into N and 4L etc. If you pop up the bezel you'll see what I mean

 

Just found this tread, and has me concerned. I have the 242 and just ordered a Hack N Tap for it, planned on keeping it for the undeterminable future, but what is this about lockers presenting a problem with the 242? Can anyone chime in on this? does this just mean that the full time will be useless with lockers, or just in general.

Also, if I get air lockers, would driving in part time with the lockers enguaged be a problem as well? obviously I could still use the full time on icy/wet roads as long as the lockers are not engaged, but this business of being in four wheel and having lockers being a problem is a little disheartening.

I invite your expertise.....

 

I'm not sure how it would pose a problem at all, if it did, it would be with the full-time option. Otherwise, it'd be no different than how a 231 would do with lockers in part-time.

 

it wouldn't be a problem, its the same as a 231, i'm fully locked with a 242 t case and have been for awhile no problems.

 

But have you used it with the full-time option?

 

My only complaint on a long-tailcone 242 with a H&T SYE is that it leaks around the washer and C-clip on the end of the flange adapter. Sealing around the shaft vs sealing around the yoke. I've learned that I might have the wrong type of SYE. I'm not giving up and have a new plan to weld the washer in place to seal the gap, or get another output shaft from the JY and weld a short piece of donor stock slip yoke where the seal rides.

wiki has a great table to let you know what is what and how to identify a t-case

242

2= 2 speed
4= strength (1-7 scale)
2=
1 = Part-time 4WD
2 = Full-time 4WD
3 = Electronic shift
4 = Not currently used
5 = Torsen-type differential
6 = Computer controlled multi-plate wet clutch
7 = GeroDisc
8 = Not currently used
9 = Viscous coupling

 

I like the 231 in my XJ. I had the same one in my TJ and it never gave me a problem. I would be nice to have the full time option of the 242 so in the rain I won't spin the tires so much. and as for the PART TIME and FULL TIME it is under stood that

PART TIME = use part of the time on snow and loose gravel were traction is at a min

FULL TIME = use all of the time regardless of the road conditions. Not really for Off road use.

 

So according to New Venture, the 242 is actually stronger than a 231. That's opposite of what I've seen just about every 231 owner say. haha

 

In order of desire if want a:
1st 231
2nd 242
And last a 249.
The 249 sucks because it has no 2wd option!! It's Full time 4wd all the time,
Why is that necessary??!!!
And that viscous coupler sucks too...
My sisters wj had it, I hate it!!!! I can't say wj with a straight face, it seems wrong....
And don't get me started on that ****ty 4.7....
4.0LHO!!!!

 

249 is not even #3. It's not acceptable at all for even semi-serious offroad.

You're correct. I can't find the specs now but according to the Max Output Torque the 231 is about 10-15% stronger.

 

this is what I found from the Novak Conversions Website about the NV231

(The standard duty OEM 231 transfer cases are capable of transferring from 1600 to 1900 ft. lbs of torque (as claimed by NVG - actual experience puts this number quite a bit higher). Wide chains, larger planetaries and stronger mainshaft/tailhousing assemblies (see Tailhousings, below) are also available if even more strength is desired. With such upgrades, a transfer case capable of handling 2900+ ft. lbs. of torque is attainable. This is a result of good engineering and refinement) http://www.novak-adapt.com/knowledge/np231.htm

This is why I like the 231 you really cant kill it.

 

Pretty sure the OP killed a 231. That's why he's asking.
