Review: OEM quality. Positions clearly labeled. Self adjusting. - Work great! Uses Lucas red grease. Straight forward, but a bit messy, install. OEM replacement. One seal got smushed in shipping, even with heavy duty boxing, but supplier sent extras ASAP. Does not include wire splices/connectors. Don’t forget the break-in process, before hitting the open road. Love the self adjusting upgrade.
Review: Great quality, all mounting hardqware is included and these were a snap to install. - These were a breeze to install on my 10' Hallmark enclosed trailer. Popped off the old hubs, installed the backing plate, greased and installed the new bearings in the drums and mounted the drums on the spindle. All parts look to be of good quality and everything needed to install was included in the hardware kit, minus the wiring on the trailer. I'll add that adding the wiring to the trailer took longer than mounting these on the trailer axle.
