How to Replace Hubs on Utility Trailers
Trailer hubs rarely fail, except under extreme conditions. Boat trailers used in salt water would be a good example of such conditions; failing to rinse the hubs with fresh water could lead to corrosion forming around the rear seal or rust formations, weakening the lug studs. The metal dust cap could erode beyond service specifications. In some cases, water intrusion seizes the bearings. In all of these cases, the hubs become useless and must be replaced.
