For a replacement grease caps, I'd need the measurement of the hub bore (the inside diameter of where the grease cap would sit). The measurement would need to be accurate to two or three decimal places, so a digital caliper like # PTW80157 is the best way to get the needed accuracy. If you don't have access to a digital caliper, if you can provide the reference number to the outermost wheel bearings, I can determine the diameter of grease cap you'd need. You can simply reply to this email.
