How Often Should Oil in Trailer Oil Bath Hubs be Changed

Published 03/07/2019

Question:

After converting to the oil bath how often do you need to change the oil and or open the hubs and inspect the bearings? Also is there an alternate oil to use from Amsoil? Thanks

The common recommendation with oil bath hubs is to not mess with them at all as long as they aren't leaking or the oil isn't milky looking. Some say to change every two years but most will say that as long as everything looks good just leave it be. Also 50 weight gear oil is recommended. I am sure there is an Amsoil product for that.
