ok i posted this a while ago and didn't get many replies...but.

i've go some newer info that may help.  a few days ago i put the tracker in 4-hi and it loped hard and the t-case shifter whiped around and eventually popped out of 4-hi and back into 2 wheel drive.  It actually felt like it wasn't quite catching.

so i got underneith today and looked around.  the t-cases mounts are solid, so no problem there.  but i went and hand turned the front drive shaft and i could turn it 180 degrees in either direction till it caught something
is it supposed to have THAT much play?

my first guess is just assume the t-case is done and buy a new one or go with one from Hawk.  but now i'm wondering if it's something else

any ideas?  has this happened to anyone else? was it just a bad T-case?

HELLLLP!?  

I just had mine stuck in 4wd, did not matter what the shifter was in.   I had to change the fluid, it was creamy white with chunks in it....water got in there on one of my expeditions.  

actually, all of you go change your t-case fluids.   it's too important

Were the hubs locked
If not the front shaft should turn with
no catching at all, if they were, might be
a broken axle shaft, or T-case chain, tho
Mike Hagen says he's never broke the chain
so that might not be it either, unless like
Bandit said, you got water and chunks in
the T-case, it might be rusted and junk inside.

well.....
it is a used truck and i doubt it ever had the fluids in the T-case changed....ever
i've done everything but the t-case last summer. (i.e. axles, transmission)  I would have done the T-case but ran out of money for more gear oil, and then ran out of enough free time to monkey around changing it out...followed by a nice long "cold" winter.

so if i change the t-cases oil you think it may work again?

and also the hubs weren't locked so i guess your right, thank God because that really worried me.
