Question:

The pre-installed inner race for bearing 25580 is not seated all the way to lip of the inner part of the hub. Is that a problem? Or is there something holding that race in place that it wont move over time further to the outside of the hub.

Expert Reply:

You will want the Inner Race # 25520 seated completely inside you Dexter Trailer Hub and Drum Assembly # 8-201-9UC3-EZ. If both the races are not fully seated when installed on your spindle they will push in over time and you will damage the bearings and your tires will begin to wear on the inside edge. You can use the 7-Piece Installation Set # PTW83020 to ensure your races are installed fully as trying to use the Bearing # 25580 to install the race will damage the bearing. I have seen races move in shipping due to the constant vibration and them being shipped on their side rather than up and down like they are once installed on the trailer.
