    You probably have the tranny in gear, putting a load on the whole drivetrain. Simply throw the tranny in nuetral and then shift the t-case. OR: You may sometimes need to roll back a little to disengage everything. This takes the load off everything while it's all in the forward motion. If you take some slack out in the backwards motion, it will allow some 'play' to allow the shifting.

    The Detroit in the back for some reason has something to do with it. A locked rear only seems to make it worse. Try what MJ said and also try rocking the truck back and forth.

    I have just about perfected the "205 shift on the fly". When I am in 4lo and need 4hi or 2wd I just keep rolling, shift into N (with the trans), shift the 205, and go back into D (with the trans).

    When I first got the truck I tried alot of ways to get it to shift (including putting my foot on the lever and pushing!) but this way was the only way that worked every time. It is also fast and better than your friends almost rear ending you because you stopped on the trail to shift!

    It is one of the tradeoffs. Strength vs ease of use. I will go with strength every time.

    I was taught that you can shift the 205 either stopped in N or rolling in gear with no throttle and by "yanking it like a man".

    Works for me.
