How about a couple of bags of sand on the front bumper - with a string
back to the cab so you can release it on demand? My experience with
4WD on ice was that other than just getting going you're usually
better off with dropping to 2WD for steering purposes. Those wide
toboggans you have on don't help either <g> - large contact area, low
contact pressure.

LOL. I wish! Unfortunately I'm pretty sure that'd violate just a rule
or two ;-)

Thanks for the ideas, guys. I had a feeling this was just going to be
a crapshoot at best, but it was worth a shot there might be some holy
grail answer (ok, not necessarily worth a shot, but what the hell?)

I did try to do the 4wd-2wd-4wd changing while driving in one of the
practices last weekend, but it didn't do as well as I hoped. I'll try
again this weekend. I probably need to get more practice timing the
changes between 4 and 2 wheel drive.

And yes, Mike, I have kidneys of steel! lol

Switching in and out of 4HI should be completely seamless. There is no
"timing" in this change. The gears are all going at the same speeds in 2HI
and 4HI, so the change can easily be done literally at the flip of a switch.
The Jeep doesn't use a switch to do this job, but it could.

Slight quibble here: if you have the rear wheels spining like mad on
the ice and try to shift with the front end rolling or plowing, it's
gonna complain. The puny little syncro in the tc can't handle the
load if the front and rear drive shafts are turning at speed that are
too far apart. You have to basically just let off as you shift so
that the wheels are all turning close to the same.
