I made a turn into a shopping center parking lot, looked back and saw one of my trailer wheels lying in the middle of the road. We have a 2011 Cougar half-ton 5th wheel. The brakes, including backing plates were replaced new last summer. I greased the bearings via the outer zerk fittings this Feb. All this and the bearing failed, breaking the drum. the wheel came off along with the broken drum.
I blame this in part to the size drum they put on these light weight trailers. Mine are ten inches across the inside center. We are careful to load light for trips, despite the 2900 lb carrying capacity which leaves me to believe the Dexter axles are way under par for this trailer which weighs about 7000 empty.
