Attwood HubMate Wheel Bearing Protectors - 1.78 Inch Bearing Covers With Grease Fitting

Hey trailer and boat owners, listen up - these Attwood HubMate bearing protectors are about to save you so much headache and money on maintenance! These clever little devices replace your standard dust caps in the wheel hub, and here's why that matters: they have this accessible grease fitting that lets you add fresh grease without taking everything apart. No more disassembling your entire wheel hub just for routine maintenance! The 1.78 inch outer hub diameter fits most standard applications, and the custom-fitted PVC covers create this perfect seal that keeps water, dirt, and all that road grime out of your bearings. What's really cool is how they create positive grease pressure inside - this basically means grease is constantly being pushed out slightly, which prevents contaminants from getting in. They automatically lubricate your bearings while you're driving, which significantly reduces wear and extends the life of your bearings. Installation is straightforward if you're comfortable with basic mechanical work - you're basically swapping out your old dust caps for these upgraded protectors. The quality is exactly what you'd expect from Attwood - durable materials that withstand road conditions, temperature changes, and exposure to elements. For boat trailers especially, these are absolute lifesavers since launching and retrieving puts your bearings through such harsh conditions. I've been using these on my utility trailer for over a year now, and the difference in bearing maintenance is incredible - no more seized bearings, no more repacking every few months, just reliable performance. They're one of those simple upgrades that actually delivers on its promises and pays for itself in reduced maintenance costs and avoided breakdowns. If you're tired of constantly worrying about your wheel bearings or dealing with premature failure, these HubMate protectors are worth every penny for the peace of mind alone.
