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.

Hey Nate, did you end up going with the Easy Grease hub instead of the Terran one? Knowing how it performed could help others deciding between those two options.
