How An Automotive Differential Works

Most of us motor heads past the age of 50, know at least the basics of how an automotive differential works, it was something we learned in automotive shop class way back in high school. Sadly automotive shop classes have disappeared from many high schools, no doubt in part because modern cars have got a lot more complicated than they were when we were in school. Even if you know how an automotive differential works... trying to explain it to someone else is more than a little complicated. It is one of those things that is simple to understand but difficult to explain. So here is a little help compliments of Chevrolet who in 1937 had the Jam Handy Company complete yet another technical film project. In this film they have done an excellent job of explaining how an automotive differential works.  Grab some popcorn and enjoy.
