These basically just hold your wheel onto the car. They’re threaded, so they screw into the hub assembly and then the lug nut tightens against the wheel, clamping everything together. Pretty straightforward, but incredibly important. Think of them as a key structural part connecting your wheel to the car. Everything—the weight of the vehicle, turning forces, bumps in the road—all gets transferred through these bolts. They’re under a lot of stress. They aren’t something you generally think about until there’s a problem, but they're vital for keeping your wheels securely attached. Honestly, if a wheel bolt fails, things can get really dangerous, really quickly. A loose or broken bolt can lead to wheel wobble, vibration, and ultimately, the wheel could come off while driving. You’ll notice if one is failing, usually through vibration in the steering wheel or a clunking sound. Sometimes you’ll even see rust streaks coming from around the bolts. Replacing a damaged wheel bolt is a relatively inexpensive repair that provides a huge safety benefit. If you're doing brake work or notice any issues with your wheels, it's a good time to check these. You can find replacements pretty easily, I’ve seen good options over at Fixparts Online, but any reputable auto parts store will have them. Your satisfaction is our mission: Wheel bolt (MPN 4.40139) includes a 12-month warranty!
