MP3022 transfer case inside pictures ??

NP242 is cool in Jeep or H1 mode. H1 is super cool with 32spline shafts and 6 pinions. Crazy strong. I wonder how 4A works with a 48/52 bias ? Basically it would have to be “locked” at that bias since there is not a clutch pack ??

I believe that in High, the 242 will spin the tire that has no traction, like an open diff but at the tcase. Basically if you have one tire in the air, you will not move unless you BTM. High Lock or Low Lock, it mechanically locks both front and rear. If ine tire is in the air, you will still move. Its why 242 wirh lockers is a great combo. Some older Cherokees have 242s as well.

Anyway, just random thoughts on different tcases.

Is 17 the clutch pack ?

Sorry away from a computer for a few days.

I think you got your answers. @Turboencabulator has got more details than me. But the actuator is not that small. Big thing hanging off the t-case.

If your t-case is having problems most likely it’s the actuator, it is the weak link. But if it is bad long enough the gears can get damaged. And if the actuator is working a lot that is when clutches wear out.
