Hm, I was told there'd be math.

That was great. Thnk you, subby.

The old GM training film?

... clicks link....

Yup, that's the one.  Best explanation I've ever seen and I was a mechanic over thirty years.

I'm partial to it, myself.

That was a derivative work.

I gave my truck an LSD and took it on a trip.

They could have integrated something new into it, but I suppose they Taylored it for the common man.

I've seen it before. It's why trikes have shifted to front wheel steering, rear wheel drive. Too damned many parts for a cheap thing.

When I first took apart a CV joint, my thought was "how did they think of making this thing?"

you've held the innards of a disassembled diff.
right there is where i stopped reading.

That was a fun watch.  The motorcyclists at the beginning made no sense.

That video come around again?   I'm ok with this - thats good solid info.

I also like the one about  transmissions.

Imo it's more safety, on hard braking 2 wheels up front won't tip, one wheel will.

Old military training films are an excellent source for basic knowledge on virtually any subject. They were deliberately produced to be simple enough so that any recruit fresh off the turnip truck could understand.

And the dramatic music an narration is a bonus. I think they probably used the same music, for everything from differentials, to electrical theory, to battle films. I'm sure, somewhere, there is a film on accounting principles that uses the same music and narrator.

And once you understand that you can move up to the Torsen differential.  It's what let Audi rule the Rally circuit after they used the Torsen in their Quattro AWD system.

Yeah, I was wondering WTF that was about. They finally got to the salient point but it took a while, for no good reason.
