Description
Wheel bearing dust caps may be small, but they play a crucial role in protecting wheel bearings from dirt, water, and debris. Common on older vehicles with serviceable tapered bearings—and sometimes on sealed rear hubs—these caps fit tightly over the bearing to keep grease in and contaminants out.
Installed after bearing adjustment, dust caps rely on an interference fit, making them secure but sometimes tricky to remove or install. Using the proper tools and techniques is essential to avoid damage, which can lead to grease leaks or bearing issues. A damaged or loose-fitting cap should be replaced promptly.
Easily available and simple to install when handled correctly, dust caps are an important part of wheel maintenance. Recommending the right cap ensures customers protect their bearings and complete repairs correctly the first time.
