Thinking about taking a used pair of unit bearing hubs that I took off and modifying them. Pressed one apart, basically a cylinder with 2 plastic ball bearing race ways, that hold two inner tubes, one splined for the axle. Thinking of drilling into the side of the hub, threading it an installing a grease fitting. One thing I would like to know is does anyone know what size hole and what tap I would use for the grease zerk? I saw on you tube and a few other write ups where guys are removing the abs wheel speed sensor, pumping in grease then reinstalling the speed sensor. Any and all thoughts and comments on this idea would be appreciated.
Thanks,
Bill
