An automobile is a true marvel of modern engineering, the product of a hundred disciplines and the brightest minds. It's also wonderfully egalitarian, as all that power and speed gets regularly turned over to idiot teenagers who pepper their sentences with "ums" and "likes" and think that the nimrods on ''The Jersey Shore'' are role models. Damn kids. GET OFF MY LAWN!
Anyway, there are lots of bits and bobbins and crazy little weevils that keep your car from turning into a slip joint as the axle moves in different directions. In other words, a yoke is one of the components that helps your car turn.
