One of the wheels on my trailer seems to be losing the grease in the BB. I've regreased it three times this season with minimal towing. One long trip but the rest have been a couple miles to the launch. Any ideas?
^^^ The seal on that side blown out and not holding the grease. I bet if you look at the back of the hub, you will see grease sprayed all over, which if you have drum brakes, means that the side with the issue is not braking with all of the grease.
