I have a question for all the gear heads out there. I recently visited a website called howstuffworks.com to learn about a limited slip differential. I understand the concept of the ring gear and the pinion gears within that spin the side gears at different speeds if needed (as in a turning or traction loss situation). However I don't quite understand the difference between an open differential and a limited slip. What kind of limited slip do we have and how does it differ from an open differential? Thanks in advance to all of those who reply.
