Sometimes these concepts are hard to get your head around. I love how simple explanations help it all to "click" in one's mind.

there's a couple minutes of "Indian Ballet" before the instruction begins.

I said on another forum where this vid was posted that I'd love to see something similar to describe the various types of LSDs...

...like a Torsen. Those things are the definition of mechanical witchcraft.

"IT IS CALLED....THE DIFFERENTIAL"

Love the style of narration. I expected a flourish of horns at that pronouncement.

I did not see where the fixed bar was leading. Nice illustration!

Torsens are powered by voodoo.

I like the 1930's homoerotic "stunting" in the first couple minutes.

The one I'd really like to see would be a cam-and-pawl. I've been having the toughest time figuring out how they're supposed to work.

Good vid, I just ran across this related one that helps explain torsen diffs:

It's impressive that they came up with things like diffs in the thirties or before (like the whole mechanics of engines and transmissions) while we still sometimes struggle wrapping our minds around the concept.

Then again I'm a touch-n-feel type of a person so until I take it all apart and put it back together it's hard for me to comprehend it.

I'd love to build model diff/engine/trans from scratch just for the heck of it...that'd be so cool. Only if I had a lathe, a mill, a tig...

I'm surprised anyone thought one-wheel-drive was a good idea I thought solid axles were used before diffs...

Oh and here's an explanation of cam and pawl diffs. They look really complicated but in concept they're so simple and primitive it's ugly:
