Bearing Buddy 2.402" Chrome Trailer Wheel Bearing Protector, 2-Pack (43402)
The Bearing Buddy is the original pressurized wheel bearing protector, built to keep water, dirt, and road grime out of your trailer hubs. This chrome-plated model fits hubs with a 2.402" bore diameter and maintains positive grease pressure inside the hub cavity — so bearings stay lubricated and protected even after repeated water submersion during boat launches. A 2-pack covers both wheels on a single axle.

Parts Desk Insights
Best Use Case: This is the correct fit for trailer owners whose hub bore measures 2.402" — a common size on mid-range boat and utility trailer axles. If you regularly back your trailer into the water, the pressurized grease cavity is what separates a Bearing Buddy from a standard dust cap: it actively resists water intrusion rather than just covering the opening. Always verify your hub bore diameter before ordering; the next sizes in the lineup are the 43401 (2.401") and the 43712 (2.717"). For trailers with drum brakes, pair with the Bearing Buddy Spindo Seal to complete the hub seal. If you want to keep excess grease off your tires and wheels, the Bearing Buddy With Bra version includes a vinyl cover for a cleaner installation.
