Guys, when the car lifted up and let the wheel rotate in the air with D gear without press on pedal, will both of front wheel run together or 1 fast and another slow?

I found that front right wheel is running but front left wheel are not, the SC told me that it was normal, but i am think both wheel shall tight together with the shaft and this shouldn't be happened.

Any experts can explain to me?

"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, such as karts, both driving wheels are forced to rotate at the same speed, usually on a common axle driven by a simple chain-drive mechanism. 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." from Wikipedia.

Based on my understanding, open differential is conventional method and LSD is advance method.

My question is, when both wheel is on the air, the reaction force impose to both tires is almost the same, i.e. nearly zero, but then how come there was only 1 tire spin while other stop at D drive?

hmm。make sense. Haha, anyway thanks for the explanation.
