It basically takes the power from your transmission – where the gears are – and sends it back to the rear wheels, or in some cases, to the front wheels if you have a front – wheel drive vehicle with a transfer case. It's a rotating shaft with universal joints at each end, allowing it to work even when the angles change as your suspension moves up and down, or when turning. It’s a pretty simple concept, but it needs to be strong and balanced. Think of it as the link in the chain between your engine’s power and the wheels actually moving the vehicle. Without it, you’d have an engine that’s running but no power getting to the driving wheels. It works alongside your differential, which splits the power and lets the wheels turn at different speeds when you go around corners. It’s part of the whole drivetrain system, working with everything from the engine to the tires. Well, if this thing fails, you’re not going anywhere. A failing prop shaft can cause vibrations, noises – usually a clunking or humming – and eventually total loss of power to the wheels. A worn U – joint can cause vibrations that’ll shake the whole vehicle. A damaged shaft itself can cause imbalance and catastrophic failure. It really acts like a shield, protecting the rest of your drivetrain from damage. You’ll notice if something is going wrong; it's usually pretty obvious. We carry a good selection of these at Fixparts Online, and we can help you find the correct one for your vehicle to get you back on the road.
