These little rubber rings seem simple, but they create a seal. Basically, they prevent grease—the stuff that keeps everything moving smoothly inside your hub—from leaking out, and keep water and dirt from getting in. They’re designed to sit in a groove and compress when parts are put together, making a tight barrier. Think of your wheel hub as the center of the wheel, where it spins. This O – Ring sits within that hub assembly, sealing around the wheel bearings and other moving parts. It’s a small part of a bigger system, but a critical one. It’s not something that makes the car go, but it’s essential for everything to keep turning properly. If this seal fails, grease will start leaking. That grease is vital for keeping the bearings lubricated, and without it they'll wear down really quickly. You'll start hearing noises—usually a grinding or humming sound—that’ll get progressively worse. Eventually, the bearing could seize up, which is a serious safety issue. You’ll notice if one goes bad because of the sound, and sometimes you’ll feel a vibration. These are cheap to replace, but fixing a damaged wheel bearing because of a leaking seal is a much bigger job. You can find a replacement pretty easily, even sites like Fixparts Online have them, and it's something a reasonably handy person can tackle themselves. It's definitely better to deal with this now than to wait until you’re facing a more expensive repair. One size fits all: O-Ring (MPN 0804721) has a 12-month warranty!
