T-Case Questions

[XXLMJ]

I have 2 transfer Cases One says 242 and the other 231 both say 272 ratio. My question is, is one better than the other? Are these interchangeable?

The reason i ask, my peugeot to a puck so i pulled it and the t-case, i have this extra t-case that came with my new ba/10. I was running the 242 before and had no problems with it. So i was planning on just sticking with it, unless someone tells me different.

You could use both of them. :waving:

 

Depend of your choice, If you plan to make some wheeling, the fact is the T-231 is stronger because less moving parts.

 

:smart:

 

T-231 is for Part-Time 4WD

T-242 is for Full Time 4WD

I'm actually planning on selling it once i piece it back together and put that money toward my other MJ that's basically rust free. So maybe i should keep the 231 for myself and put the 242 back in my rusty MJ.

What do you mean by Part Time and Full Time?

the Military uses the 242 in the hummers

what's the spline count on the inputs?

The 231 is a 21 and i haven't separated the 242 and the BA/10 to count yet, unless there is a different way?

One came out a 89 MJ and the other a 89 XJ I was assuming they were both 21 but like i said i have checked both yet.

you've got a 242 mated already mated to a manual trans? interesting. well, the good news is that it should be 21 spline since the peugeot is.

 

I'd keep the 242. all-wheel-drive means you can use it on dry pavement without breaking anything. :D the 242 also has a part-time setting, so it's got every choice possible. :thumbsup:

 

 

part-time: loose surfaces only

full-time: any surface
