No 4 Lo

Went wheeling today and couldnt get the front driveshaft engaged.I was in 2Lo.
4Hi worked fine (both axles spun)
but the front shaft wouldnt lock up in the Dana 20 case
when I shifted to Lo gears
The rear wheels spun, but the front was disengaged
Any ideas?

Re: No 4 Lo

I had this problem, and it ended up being a bent linkage and loose connections on the shifters themselves. A little tightening and replacing a couple cotter pins out on the trail, and I got it to have 2wd low (like yours is running now) and shift one click further forward to 4wd low. I just left it that way! It was nice to have the 2wd low option - even if it was only to the rear wheels and with one stick! I ran it that way a couple of years till I got a 300 and never burnt anything up or broke anything. In fact, I had to pull the 300 out for some work, and I when I put the 20 back in, it still worked the same way! I am not saying this is the CORRECT way of doing it, I just did it that way to see if it would work or not. It did for me.

If you bend this linkage and get stuck out on the trail with this, take a small hammer and GENTLY tap the top arm into gear while rotating the front driveshaft slightly back and forth. You won't have any problem slipping it out of 4wd low - the problem is just getting it to go in!

Re: No 4 Lo

So the top slide controls the front axle, and if I tap it in, towards the case, it sould engage the front driveshaftin 4 Lo?

Re: No 4 Lo

Yes if I remember right it is the top one . . . but it has been a while. I keep saying top - it sits in there at about a 45 degree angle or so - it will be the top-outer-left one as you are looking at the front of the case. But you will be able to tell because it will be sticking out about 1/4 of an inch or so further than the other one. Have someone sit inside and shift between the ranges. You will see for sure which one it is and see the slop in the linkage. Yes if you GENTLY tap it in (with the t-case selector in 4lo and the transmission in neutral) while you rotate the front driveshaft back and forth by hand it will engage the FWD - that is unless you have something severely toasted in the t-case. But with it being a D20, I'd just about bet that the bent/loose linkage is the cause.

Re: No 4 Lo

my new YJ with the NP231 doesnt have 4L either. Also, mine doesnt have N either. The shifter will only go to the 4H and 2H position. I hope this isnt serious. I will look soon

Re: No 4 Lo

Just want to say thanks to all for the help
It seems that the front axle rail doesnt slide in the case and leaves me with a 2LO option. I can tap on the rail and slide it in as it should be. I think I will leave it like this and see how it does. Just wanted to say thanks for all your help people
