0BK409345C Audi STUB SHAFT

This part connects directly to the gearbox and it’s essentially what transfers the power from the gearbox out to the driveshaft, and eventually to the wheels. It spins, obviously, and it’s designed to handle a lot of torque—that’s the twisting force that gets your vehicle moving. It also has splines—those grooves you see—that lock it securely to the components it connects to. Think of it as a crucial link in the chain that gets power from the engine to the road. The gearbox changes the gears, and the stub shaft is the first thing that takes that changed power and sends it outwards. It’s part of what allows the wheels to turn at the right speed and with the right amount of force. It’s right there at the output of the transmission, connecting it to the rest of the drivetrain. If this thing goes bad, you’ll definitely notice. You’ll likely feel vibrations, especially during acceleration, or you might hear clunking sounds. It might also cause difficulty shifting gears, or even complete loss of power to the wheels. It’s a pretty strong part, but it’s under a lot of stress, so it’s not immune to wear and tear. It acts like a shield for some of the more sensitive components inside the transmission, absorbing a lot of the shock. If you're doing a transmission rebuild or a major repair, it’s a good idea to replace it preventatively. You can often find them on sites like Fixparts Online, along with everything else you'd need for that kind of job. It’s one of those parts you don’t think about until it fails, but when it does, you’ll know it. Long-lasting performance: Stub Shaft (MPN 0BK409345C) is backed by a 12-month warranty!
