Dana 20 xfr case 2 lo?? or I\'ve got a problem...

Can anyone help me out with this one - I was up a trail between Panamint and Death Valley this weekend and got pretty far...my buddy with the FJ40 was watching and said the front end seemed to be doing nothing. It wasn't. (He got up - I didn't...bad form for me.) We got back down and I figured I had something wrong with the front end drivetrain or xfr case. Now that I've read some posts I've seen a few people talk about the phantom 2LO position in Dana 20 transfer cases. When I troubleshot the problem, I thought I had it in 4LO and the front driveshaft was not moving. The other part of this is I cannot seem to get the thing into 4HI. Bottom line - do ya'll think the case is busted or I'm a dumb** and can't figure out the shift pattern? If so is there any tricks to getting the dana 20 shifted into 4WD?? Thanks for any help!

(It's a 73 CJ5 with a Chevy 350/turbo 350 tranny + stock dana 20 xfr case)

I am one of those people with the phantom 2 Low. Just making sure you're shifting it right it goes like this

4 High
2 High
Neutral
(2 Low if you've got it)
4 Low

Try shifting as you slowly creep forward. It usually works for me. If you can't get it to shift then I'd venture that you've got a problem.

There is a position just in front of of 4 Lo that gives you 2 Lo. It shows up after a certain piece becomes worn out.. don't recall what that part is, but I'm sure someone here will stpe in and say. anyway, Yes there is a 2Lo, but it wasn't really ment to be there. As for 4 Hi issues... can you not find it, or can you not shift into it?

Make sure your shifter has enough clearance for 4 hi and 4 low. Sometimes body lifts or shifting of the body prevents the shifter from being able to go fully forward and reverse. Otherwise climb underneath and take a look. You could have just lost or broken a cotter pin holding the front shift rail to the shifter. The front shifter rail is the one closest to the passenger side.

Great advice - the shift boot was actually restricting the both the 4HI and 4LO. Problem solved! As a note to other unsuspecting Dana 20 owners, the shift lever is almost straight up when in 4LO and almost flat on the floor in 4HI. At least that's how it is in the CJ5.
