Have no idea. Car developed some issues and noises which slowly got worse and worse. Sharp turn followed by hard acceleration caused the entire car to shudder hard. Like teeth skipping. This must’ve been due to the maneuver activating the differential action. Besides that, there was simply a thump noise, increasing in frequency with speed. Almost like a bad wheel bearing. Amazingly, I was still driving the car and it was moving. Once again, how this happened, I do not know. No damage to the casing either.
