A sleeve is basically a cylindrical liner. It fits inside another part – usually a bearing housing or a similar opening – and provides a smooth, precise surface for things to move against. Think of it like a really well – fitted, super – smooth bushing. It can also help protect the surrounding material from wear and tear, and keeps everything properly aligned. Where it shows up depends a lot on the vehicle, but you’ll often find them around the crankshaft, connecting rods, or in suspension components. Sometimes it’s inside a steering knuckle, other times it's protecting a valve guide. It's really there to handle friction and stress in moving parts. They aren’t always visible without taking things apart. It's important because without it, metal – on – metal contact happens. That causes friction, heat, and eventually, major damage. The sleeve acts like a shield, preventing that direct contact. You’ll notice if a sleeve is failing because you’ll probably hear noises – knocking, rattling, or grinding – and performance will drop. Things just won’t move as smoothly. A worn sleeve can quickly lead to bigger, more expensive repairs if left unchecked. You can find a pretty good selection of these at places like Fixparts Online, but honestly, the key is getting the right size and material for your specific application.
