What is an open differential and how is it different/better? How can I tell if I have one?
An open differential basically transfers power to whichever wheel resists it the least, IE, whichever wheel has LESS grip. So, if you have one wheel in snow and the other on pavement, the one in snow is going to spin all day and the one on pavement won't be receiving ANY power and thus sitting still. The only situation in which both wheels will get power is when they have an equal amount of grip.
Its the easiest, cheapest way to do a differential basically.
Fun fact: The 34 gallon fuel tank in this style of Chevy truck is located on the drivers side of the bed, right before the wheel, so, with the extra weight on the drivers side, the drivers side rear wheel has more grip. Therefore, when you do a burnout in these trucks (if you have an open differential) the passenger side rear wheel always has less grip and thus always is the one to spin.
