i just purchased a boat with a tandem axel trailor. the left rear tire on the way home after about an hour on the road heated up to the point grease was oozing out all over the rim and the hub was to hot to even touch. i tore the bearings out today and was wondering if it was indeed the bearings causing this to heat up or if there is something else i need to do and if it was the bearings what i need to do and how i need yo pack the bearings back in and get this to end the problems. the trailor has trailor brakes but i do not have the trailor hook up in my truck could this have caused this and if so how i could disable the trailor brakes to keep them from catching. thank you for all help
If the heat was caused by the bearings, they should be slightly discolored. On my tandem axle car hauler, I installed grease caps with zerk fittings on them. Before each long trip, I get out the grease gun and give each about 15 pumps. Since yours gets exposed to water, I would pull all and repack, looking for signs of corrosion, pitting or rust, and discoloration. Replace as necessary with new seals. Get the greasable caps.
