Please specify the details when asking questions in the comments. Don't just say "mine doesn't work". Instead, you can say "this part is not spinning" or "some parts fell off", anything, depends on your problem :) A differential is used to make each left and right wheel able to rotate on different rpms. These different rpms are used while turning/steering the vehicle. When a vehicle is turned, it requires each left and right wheel to spin at different rpms or else each wheel will need to slip everytime the vehicle is turned. Differential advantage: - Allows for sharper turns - Makes a car turns so much faster (depending on how wide your car is) - potentially increased top speed due to independent wheel rpm Please expect your questions delayed to be answered sometimes, in the meantime while waiting for your question to be answered, ask some of my fellow engineers friend such as Noodle, Cr4zem, Vladik, and others!
