So I drive a Sidekick. When it's really slippery (snow), I drive in 4H.
When I brake aggressively, it definitely resists wheel lock up better in 4H than in 2wd. (No ABS)
I *almost* get what must be happening, but I need someone else's words to clarify I have it. Or "have" the last 5%.
The outputs to front and rear axles have to be the same at the transfer case.
The diffs are open ones.
So when one wheel locks, the other has to either spin 2x as fast- which isn't going to happen, or.... or what? An engineer would say, the total RPM of any axle pair of wheels has to equal the other axle pair.
But I'm still not intuitively getting it. Talk me through it- the backwards torque, etc?
