Stuck on Ice

LSD operates this way but any locker will move just fine with a wheel in the
air. TG

I googled it a while back and saw the same thing... follow the link(s)
bellow. Check out point #4.....

Interesting...sounds like I had it

Thanks for that Mike. At one time I thought I had a good search method, but I wasn't able to find
what you did.

How did you do it?

I think I'm beginning to understand it better myself. I was wrong to say that the Hummer uses open
diffs, but apparently the Torsen reaches a point at which it can't compensate any further and and
goes "open". A one front and one rear on glare ice scenario would probably qualify. I think
Detroit lockers are an option.

It's all in the link.... ..."+Gleason+Torsens+air&hl=en&client="
I just searched ---Gleason Torsens air--- and there it was....

OK - I read the article about the different types of differentials, but
I don't think the advice to use throttle and brake applies to to the
original poster's situation. The poster's Impreza has an open diff.
From reading the article the brake method would only work with a
torsen. Or am I missing something?

It works by biasing the resistance to movement between left & right more closer to even. In other
words it evens out the resistance to movement.

It's slightly wasteful because it's adding resistance to the traction wheel(s) as well as the
spinning wheels, but it will get you moving. It's more effective with open-diff AWD than with
open-diff 2WD.

VDC is essentially a more sophistocated version of the same thing. It allows momentary blipping of
the individual brakes of the spinning wheels to bias some torque back towards the wheels with
traction.

Some folks preffer a manual trans in snow because of the greater control it affords them. Likewise,
some folks preffer open diffs with the option of applying some brake for the greater control it
affords them.

Different strokes. -Danny

Then what good is AWD?

You have a wheel in the front and a wheel in the back that can give you
forward movement. Seems like a good deal to me, over and above any FWD or
RWD vehicle.

Caveat emptor! Anyway go buy a WRX--it has limited slip rear, and a
center differential too. Very nice in snow.
