Tongue and coupler
Look for cracks near welds, bent tongue sections and a coupler latch that closes firmly. Rust pitting and flaking near the coupler can hide fatigue cracks.
Safety chains and breakaway cable
Chains should be intact with strong links and secure attachment points. Crossing them under the tongue helps catch it if the hitch fails. The breakaway cable should be connected and undamaged.
Frame and crossmembers
Walk around and look underneath for cracks, bends and fresh rust streaks near welds. Crossmembers that are rusted through or sagging need repair before loading.
Axles, springs and tires
Check spring hangers, shackles and axle mounts for cracks. Tires should have good tread, no bulges and correct pressure. Uneven wear can point to bent axles.
Lights, brakes and decking
Test all lights and brakes. Deck boards or plates should be solid and secure. Ramps and tie-down points should be sound.
When to call a welder
Cracks, bent frame parts and failing hitch welds all need repair before towing. A mobile welder can often fix these at your location and reinforce the weak area.
If you see a crack in a trailer frame or hitch, do not tow until it is repaired.
