These bearings sit inside the engine block, and they allow the crankshaft to spin smoothly. Think of them like little cushions, or really smooth pads, between the crankshaft and the engine block itself. They support the weight of the crankshaft and transform that up – and – down motion from the pistons into the rotating power that eventually gets to the wheels. The set includes multiple bearings – usually upper and lower halves for each main journal along the crankshaft. Well, everything really relies on these. They’re absolutely fundamental to the engine running. The crankshaft is the heart of the whole thing, and these bearings keep it spinning properly. Without good bearings, you’ll lose oil pressure, things will vibrate a lot, and ultimately the engine will fail. It's a core component that makes the engine function. They’re important because they prevent metal – to – metal contact between the crankshaft and the engine block. That contact would cause serious wear and tear, leading to engine damage. Over time, these bearings wear out, especially with oil changes being skipped or if the oil gets contaminated. You’ll notice if they're going bad – usually a knocking sound from inside the engine, especially under load. It starts subtle, but gets progressively worse. Ignoring it is a really bad idea, because it can lead to catastrophic engine failure. A set of these isn’t too expensive, and doing them now can save you a lot of money and headaches down the road. You can find a good quality set, like this Main Bearing Set VW PDE 4 Cylinder, at places like Fixparts Online. It’s one of those parts where preventative maintenance is definitely worth it. Dedicated support: Main Bearing Set VW PDE 4 Cylinder (MPN 77553600) includes a 12-month warranty!
