This part’s job is to transfer power from your transmission or differential right out to your wheels. It’s a pretty simple idea, but it has to do it smoothly, through all the ups and downs of the road, and while your wheels are turning and steering. It's actually a shaft with a couple of special joints on the ends, those joints allow the axle to bend and move with the suspension and steering, and still keep power flowing. Think of it as a key piece connecting your engine's power to actually getting the car moving. It’s part of the drivetrain, which is everything from the engine to the wheels. Without a good wheel shaft, you won't get power to the wheel, and that wheel won't turn. Usually there’s one for each driven wheel – so front – wheel drive cars will have two, rear – wheel drive will have two, and all – wheel drive or four – wheel drive will have four. It’s pretty fundamental to getting you going. It’s important because if it starts to fail, you’ll notice. Usually it starts with a clicking or clunking sound, especially when you’re turning. That’s the joint wearing out and not being able to smoothly transfer power. If you ignore it, it can eventually lead to a complete failure of the axle – meaning you lose power to that wheel entirely. That’s a safety issue, and it can be a real pain to deal with on the road. A failing wheel shaft can also cause vibrations you feel in the steering wheel or seat. We carry these parts at Fixparts Online, and a good one will keep things running smoothly and safely. It’s one of those things that, when it's good, you don't even think about it, but when it goes bad, you absolutely know.
