5Q0521101BK Audi propeller

This part’s job is really pretty straightforward. It takes the power from your transmission – where the gears are – and delivers it to the axles, which then turn the wheels. It’s a rotating shaft, and it handles a lot of torque, which is essentially the twisting force that gets the vehicle moving. It’s a mechanical link, constantly spinning when the car is in motion. Think of it as the bridge between the engine’s power and actually getting the wheels turning. It's most common in rear – wheel drive and four – wheel drive vehicles. Front – wheel drive cars don’t typically have one because the transmission is integrated right into the axle assembly. It connects to the differential at the axle, allowing the wheels to spin at different speeds when you’re going around corners. It’s a pretty crucial piece of the puzzle. If this thing goes bad, you’ll definitely notice. You'll likely feel vibrations, especially at higher speeds. It might sound like a clunking or humming noise coming from underneath the vehicle. In serious cases, it can cause a complete loss of power to the wheels. It basically acts like a shield protecting your transmission and axles from taking a direct beating, so keeping it in good shape prevents a lot of bigger, more expensive problems down the line. We carry a good selection of these at Fixparts Online, if you're looking to replace yours, and have options for different makes and models. Backed by experts: Propeller (MPN 5Q0521101BK) comes with a 12-month warranty!
