A trailer that is never serviced becomes a story at the boat ramp. This hub is the yearly schedule, the bearing job, and the rust habits that decide whether a galvanised chassis lasts twelve years or four.
Rust on Australian trailers is a washing and drainage problem as much as a coating problem. Galvanising buys time; trapped mud, timber floors, salt and coastal parking take it back.
On Australian trailers the hub, the tyre and the brake share heat and water. Treat them as one rotating assembly — especially after salt water, corrugations and a long inland run.
Australian trailers fail after beaches, corrugations and a summer of sitting, not on a calendar. A useful yearly schedule is seasonal and kilometre-based — bearings, brakes, lamps, couplings, tyres and rust in that order.
