Here I start dismantling or tearing down the Tesla Model 3 Rear drive unit or motor. After splitting the case open we find out what actually caused the catastrophic internal failure. We could clearly see all the gears and gearsets where still in good shape. The case had a hole busted out the top and a bearing race was torn out. After looking a little more closely I found the main bar in the differential gearset to have slipped out of place. The keeper or roll pin holding the main bar in place had sheered off. This caused the main bar to protrude out the gearset and damage multiple components inside the housing. As it spun around enough to break things out of the way the noise stopped and had me fooled that anything major was wrong. I'm hopping this was more a fluke and not a major flaw in the Tesla rear drive unit and should not be common. As Matt said it probably had "One too many launches!"
Thanks for Watching,
