These unit bearing locking hubs are easily greaseable through the ABS port. The recommended maintenance schedule for all manual locking hubs is every 24,000 Miles or less. Ultimately, our manual locking hubs can possibly last the life of your vehicle with regular maintenance. NOTE: Failure to properly maintain your bearings can result in the premature wear of your unit bearing locking hubs! Simply put, all bearings can fail from neglect or lack of applying grease at regular intervals. The design of our locking hubs has simplified the maintenance process by using the ABS access port for greasing your hub, making it straightforward and effortless.
