These are essentially these little metal cushions that sit between your crankshaft and connecting rods – and also between the crankshaft and the engine block itself. They allow those parts to move smoothly against each other. They don’t just let them move, though, they control how they move. They manage the load and keep everything aligned. There are main bearings, which support the crankshaft in the block, and connecting rod bearings, which connect the connecting rods to the crankshaft. They’re right at the heart of what makes your engine run. Every time your pistons go up and down, these bearings are what translate that motion into turning the crankshaft. Think of it like a really precise, contained sliding action. Without smooth bearings, that motion becomes rough, inefficient, and ultimately damaging. They’re absolutely critical for converting the energy from combustion into usable power. Because they’re under a constant, tremendous amount of stress and friction. Over time, they wear down. If they get too worn, you’ll start hearing knocking sounds coming from your engine. It’s not a good sound, believe me. If left unaddressed, worn bearings can cause serious engine damage – even total failure. You’ll notice if they’re going bad – usually a deeper knocking than normal, especially under load or when accelerating. Regular oil changes help, but eventually, even with good maintenance, bearings will wear. Luckily, replacing them isn’t a full engine rebuild, but it’s definitely something you want to stay on top of. You can find a good selection of engine bearings at places like Fixparts Online, and they have helpful diagrams if you're doing this yourself, or you can always get a mechanic to handle it for you.
