before I need 4wd, I throw it in neutral and coast to a stop. lock the hubs, and then rolling at a slow speed, lightly blip the throttle as I pull the T case into 4HI (if it doesn't just slip in). put it in 4low when you are at a complete stop, or rollin reeeal slow. just reverse all that to get it back to 2wd. The general idea being to keep any tension off of the driveline while you're engaging/disengaging gears.
with an automatic like ours, I'll use 4 low whenever I'm just creepy crawlin around, or feel like getting the front wheels off the ground.
even if you have the power in 4hi, it'll build less heat in the trans if you use low.
If you have the original J shift, toss that POS and either twin stick it, or get an "updated version" from J.Duff. I got the Duff version and it's much much better than the old one.
Have fun!

What is the difference in the Duff version? Do they just swap the front off a J onto the T and twin stick it? or do they do other mods?

You have a lot of info but I'll add mine. I lock my hubs in at home if I think I may need 4 wheel that day. Usuallu middle of OCT during deer season and take them out at the end of nov, that being last of Elk season. When there is solid ice or snow on black top I run in 4H. Steering and brakes work much better. Don't run in 4 wheel dr on dry pavement or dry dirt if possable.

it's still a single stick, but instead of the ball in socket arrangement, it's got through bolts so it pivots on 2 axis', and is spring loaded. shifts in the same way, but a lot more positive feeling. as far as I've been able to tell, I'm pretty much the only one here to use it. everybody else uses twin sticks.
I just tried to find it on Duffs' site, and couldn't find it!
