Re: Snow-crawl on steep incline--LONG
That is true too. The trick is to find that crucial balance where the engine
is both the Go and the Stop, or sometimes the best one can hope for is Slow
Down.

Amen! Being a good Texas redneck, I thought I had seen it all - sand,
mud, even sheet ice. That first year in Wisconsin I got to the top of
a south facing hil just as the sun went below the trees, dropping it
into shadow. Instant ice! Suddenly, my dead stop turned into a slow
slide. I didn't have enough traction, even with the slight crown, to
pull it into the ditch. Most helpless feeling in the world.

Up at elk camp this last season, there was one trail into the wilderness area
that, upon scouting, we realized that NO ONE was hunting. Partly it was
because the trail itself was brutal with all the blowdown and deep snow, but
partly it was because the only road to the trailhead was just plain terrifying.
So we, of course, hunted it hard <g>. Whoever "made" that road should be
forced to drive my TJ across it. It was pure ice and tilted slightly outwards
into the abyss, instead of tilting into the hillside. About a 2-foot
"shoulder" that was just the snow that wasn't compacted by tires. Jay-sus, it
was scary. The Jeep would be inching it's way sideways the whole time as I
crawled across in 4-low WITH CHAINS ON the front tires.
I agree with Mike... it can seem really easy to drive on ice when you are not
doing it. Sometimes, when you ARE doing it, you are just plain screwed; the
rig is on the verge of getting away from you and that's just how it is!

Re: Snow-crawl on steep incline--LONG
Absolutely NOT.
Once you *start to slide/slip* on ice or snow with the vehicle in 4WD
the different speeds of the front and rear axels will prevent at least
two wheels from gaining traction/adhesion. For example a 411 rear
differential will be matched with a 410 front differential .... one is
either pulling or dragging the other, front and rear ARE running at
'different speeds'. The difference in wheel rpm is small, but is still
different.; Its probably the reason that a 4WD once it starts to
slide/slip (on ice or hardpack) is much harder to recover than a 2WD.
No problem when there is traction and idling down in 4WD; but, when
there isnt sufficient traction, feathering the brakes in neutral will
usually allow faster recovery ... but like I stated the brakes had
better be applying the same torque to all wheels.

Re: Snow-crawl on steep incline--LONG
Absolutely NOT.
Once you *start to slide/slip* on ice or snow with the vehicle in 4WD
the different speeds of the front and rear axels will prevent at least
two wheels from gaining traction/adhesion. For example a 411 rear
differential will be matched with a 410 front differential .... one is
either pulling or dragging the other, front and rear ARE running at
'different speeds'. The difference in wheel rpm is small, but is still
different.; Its probably the reason that a 4WD once it starts to
slide/slip (on ice or hardpack) is much harder to recover than a 2WD.
No problem when there is traction and idling down in 4WD; but, when
there isnt sufficient traction, feathering the brakes in neutral will
usually allow faster recovery ... but like I stated the brakes had
better be applying the same torque to all wheels.
