Hi Nate; the Terran Axle Trailer Idler Hub Assembly # TX33VJ uses the standard 3,500 lb bearing combination and grease seal. It has a # L68149 inner and # L44649 outer bearing with a # 58846 (10-19) grease seal. If you're looking for a replacement hub I recommend getting the Easy Grease Trailer Idler Hub Assembly # AKIHUB-545-35-EZ-K instead. The Terran hubs recently showed up and we found they aren't fully pre-greased. Also, a specific grease is used that isn't compatible with most on the market so you would have to completely clean it out and add grease again before using the hub.
