This kit includes everything you need to replace your bearings and keep your board rolling as smoothly as possible. We recommend you watch our video on how to replace your bearings if you haven’t done it before. Take care to avoid over-tightening the axle nut or you could damage the bearing shields. Tighten just to the point where the wheel can no longer laterally move along the axle. Please watch our instructional service video completely before changing your bearings.
