These bearings are essentially the support system for the crankshaft inside your engine. The crankshaft is what turns and ultimately powers the wheels, and it doesn't just spin freely in the engine block. It sits on these bearings—there's a set of them, usually five or more—and they allow it to rotate smoothly with minimal friction. They handle a lot of stress and pressure from the pistons firing and the whole engine running. They manage both radial loads—that’s sideways force—and thrust loads, which are forces trying to push the crankshaft forward or backward. These bearings are a core part of the engine’s bottom end. They directly affect how efficiently the engine transfers power to the drivetrain and, ultimately, to the wheels. A healthy set of main bearings means a smoother running engine and better performance. They're tucked away inside the engine, so they don’t directly impact things like braking or steering, but if they fail, the engine won't run. These bearings are vital for engine longevity. They prevent metal – on – metal contact between the crankshaft and the engine block. Think of them as a cushion, protecting those expensive parts. When they wear out, you’ll usually notice it first as engine knocking, especially under load. It might start subtle, but it quickly gets worse. If you ignore it, things can escalate very quickly—potentially leading to catastrophic engine failure. Replacing them is a fairly involved job since you’re inside the engine, but it’s far cheaper than a full engine rebuild or replacement. We carry a good range of these, and you can find this set, and others, over at Fixparts Online. Just something to keep in mind when you’re ready to order. It's generally a good idea to replace these whenever you're doing major engine work, even if they don't seem completely worn out—preventative maintenance is key. Quality you can count on: Main Bearing Set VW EA111 4 Cylinder (MPN 77534600) comes with a 12-month warranty!
