As we know, rust is the horror story that happens all too often. It sends vulnerable parts like your axle off into oblivion becoming an expensive failure. Knowing where rust strikes the most and how to prevent it can keep your trailer on the road that much longer.
The axles and springs get the brunt of it
These components are under constant threat from road salt, mud and moisture. After driving in the snow, wash your leaf springs and axles thoroughly with plenty of fresh water. Cover with marine-grade grease and spray all exposed metal surfaces down with rust-preventative.
Coupling mechanisms need special attention
The trailer coupling is exposed to the weather and also subject to constant stress. Keep the ball joint clean and well lubricated. Do not let them seize – apply copper grease, and check for rusting once a month. In no time at all, small rust spots develop into seriously compromised main supports.

Brake components hide dangerous corrosion
Moisture and debris are sealed in by the brake drums and backing plates. Check and clean brake assemblies after annually removing wheels. Do not gamble with your life or the lives of others on a worn brake line; replace corroded lines immediately.
Chassis rails: Your trailer’s backbone
Be particularly watchful for rust bubbles on the chassis rails around weld points and bolt holes. Inside, the internal-unit housing is a real killer as it can hold water and rot from within. Degrease well, treat visible surface rust with a good quality of red rust primer, then undercoat.
Electrical connections fail fast
Lighting can fail from corroded wiring – a safety hazard. Make sure you clean all connections with dielectric grease and replace damaged cables soonest. Most corrosion problems are prevented by using waterproof junction boxes.
