So i swaped my np 207 that didnt work cuz of the chain.... i swaped it for the 242 and everything went pretty good other than it was a pain in the *** i figured out a way to hook back up my speedometer and got a drive line hooked up and all that good stuff.... but when it is in 4 wheel drive you can see that the front drive line is being torqued on but no power to the tires is this due to the locker thing on the 1986 command trac? if so how to i fix this or rig it to make my 4x4 work??????

Its because the np207 has a vacuum switch and the 242 doesnt, since u dont have that switch the front axle disconnect wont engage, so you can do a few things, you can get the posi lock kit or you can swap out the two piece axle with a 91 and up one piece axle shaft. In the mean time if you need 4 wheel you can always just pull the axle shift fork from the axle and manually shift over to lock it

The round thing that has like three wires coming from it from the axle on the passanger side??
is this the kit>?

Yes to both your questions, going ahead and search it on here, theres lots of threads talking about the posi lok setup

don't waste your money on that kit. i've had 2 of them for the same jeep. never worked like it should. huge pita on the trail when you're pulling it apart to just manually lock it in place.
i ended up just using a gear clamp up against the shift collar to hold it locked into place. that 60 cent gear clamp worked a lot better than that 200 dollar cable.

take that money and replace the whole axle with one from an abs equipped jeep. you will get the solid one piece shaft with the larger 297 joints.

^^x2, I recently went the solid axle route, which turned out to be more work than I planned. This was because I had to install new axle seals in a new location. I had to fabricate up a new axle seal for the passenger side, cuz no one made a seal that is a perfect fit. Due to there not being a seal offered, you'll see fluid leaking out of most axle housing that have had the solid axle installed.

Is there any way to rig the vacuum thing without buying that piece???

kamuela710

so i take the round thing off the axle that is connected with four bolts on the passanger side and than what? is a crap ton of oil goin to leak out??

Pain to rig it is a vacuum in and vacuum out (be easer if it were spring loaded) might be able to get the factory style switch and rig something up

kamuela710

Do you know witch color is in and witch is out?? or some simple way to rid the damn thing where i can engage and disengage it???

dont the 242 have a electric swith that screw into the case for the light if its the same thread screw the vacuum switch into that ,then it will activate it that way ?

kamuela710

ive done that but it still wont engauge the front axle the old transfer case did right before i swaped them so i know its somthing with the vacuum ****
