well toasted another 242

bcmaxx · Jul 23, 2008

Started having problems with my np242- when I had a t/case drop installed in my jeep, I managed to damage the teeth that engages 4wd. A year later I am having problems keeping it in 4 part time- low or high. just pops out and grinds. I plan on purchasing and installing a novak t/case shifter. Is it really worth buying another 242? Will a 241 work? What will fit behind my 1989 aw4? Wish there was a sticky for this.:repair: :banghead:

im pretty sure you could use the 231, theres enough guys that have swapped it to research on. the 231 has way more aftermarket support. plus i think t cases at picknpull are like 60$ on 25% off wedsnday

If you could find a 21 spline input for it. I don't know if they use a different gear than 231's, 242's.

I just built this little baby for my 89. :yelclap: NP-231, swapped a 21 spline input, Tera SYE and 2 Low kit....

Just did this swap on my 88. As long as it is the right spline count it is no problem. I went to the junk yard and picked one up for an 87-90 for $75 and put an SYE in it before I installed it on my jeep. Just make sure you get the linkage for the 231 because it is a little different although I think you can adjust the linkage already there to make it work.

Does rear driveshaft length differ?

Didn't on mine. But I used a front driveline out of a 92 and it worked just fine and I don't have my lift on yet but it still worked just fine.

That linkage had me wondering. I haven't swapped it in yet and I was curious if the setup from my 242 would work with the 231......

Picked up a 231 with 70,000km for $100, much cheaper than the $450 they wanted for another 242, I will try and make my 242 linkage work. My re1801 hack and tap will swap over until I decide to go with a hd kit with a new shaft. couple questions:
-can I use my 242 speedo gear on the 231? It's bang on with my 4:10's and 33's
-I can now install a front locker because I have no fulltime feature now right??
I can't wait!!! no more embarressment POPPING OUT OF 4WD ON AND OBSTICLE!

Just wondering, but what was your hangup on the front locker? I see no reason why the fulltime feature would of stopped you from adding one........?

I was told I could only go limited slip in the front with a 242. A locker would bind things up when trying to turn, and We get four months of pretty deep snow.

Ordered the tera 2 low kit $200 -sound fair? and there is a 4:1 kit for $750, auusi's are backordered right now $325- fair?

Got my Tera 2 low for 25 less.....but it helps that I used to work there

I'd say that's average consumer price though.

Someone else might be able to answer that, but with a 231 I would think it would cause more binding on the street than the 242. The 242 would at least differentiate in FT, front and rear.

Or I've gone nuts

well toasted another 242
