On my way home from my evening class tonight, it was pouring rain on the freeway, and I realized how nice it would be to have power to all 4 wheels (missing my Rover I guess you could say), and wanted to know if there is a conversion for making the 231 a full time / adding in full time to it, or a simple way of swapping in a 242?

 

No way to make the 231 full time.
I think a 242 swap is pretty simple, but maybe someone will post that has done it.

ANNNNDDDD..... If you want to get technical, theres really only power going to two tires unless you have f/r lockers.

 

This is true for both TC's.

 

Just make sure the input shaft is the same length and same spline count and change your shifter.

 

yup, swap one in. its fairly easy. i love my 242.

 

So pardon my hijack, but what's the difference between 4WD part and full time?

 

X2 on the shaft, there are lots of different 242 combinations so make sure its out of same tranny and engine...Tj

 

Some jeeps came with full time which is capable of having 4 wheel drive (Not Locked but slipping) while driving on the pavement as well as off road. You would need to "lock it" in 4 wheel for best performance...Tj

 

Ok, so I've got PT and FT. Which should I use for what?

 

alright thanks a lot, so other than just the tc and the shifer and plate would I be need anything else? and logan, part time is for off road or minor on road use only in slippery conditons,full time can be usedon pavement

 

PT or 4HI or 4LO = NEVER on pavement, FT = ANY TIME.

4FT Full Time is ment for the street. The TC has a Open Diff, so supplies most of the power to the rear unless traction is lost then transfers to the front. Part Time locks the TC dif, spliting power front/rear

 

Yes just make sure its the same and your good to go. There is alot of different np242s out there.
