A vehicle's wheels rotate at different speeds, mainly when turning corners. The differential is designed to drive a pair of wheels while allowing them to rotate at different speeds. In vehicles without a differential, both driving wheels are forced to rotate at the same speed. When cornering, the inner wheel needs to travel a shorter distance than the outer wheel, so with no differential, the result is the inner wheel spinning and/or the outer wheel dragging, and this results in difficult and unpredictable handling, damage to tires and roads, and strain on (or possible failure of) the entire drivetrain.

Because of recent spam attacks on Mediawiki sites by the tens of thousands of spammers concerned with the length, girth and hardness of our Johnsons, we have had to temporarily disable new registrations and editing until measures can be taken to ensure there is no further vandalism of this site. We apologize for the assholes out there that don't have better things to do, and will find a work around soon. Meanwhile, there are still thousands of MoparWiki pages containing a wealth of information.
