What to Check When Buying a Used Trailer in Australia
A careful look before you buy can save you thousands, and it's also what lenders want to know. Here's what to check on any used trailer.
Paperwork first
- PPSR search. Run it on the VIN or serial number. It shows whether there's finance owing and whether the trailer has been reported stolen or written off.
- VIN and plates. Make sure the VIN or serial number on the trailer matches the registration papers. Look for the compliance or build plate, and check it hasn't been tampered with.
- Registration. Check it's current and in the seller's name, or find out what's needed to register it in your state.
- Service records, especially for larger trailers: bearing services, brake work and any repairs.
Chassis and body
- Look along the drawbar, main rails and crossmembers for cracks, especially around welds and spring hangers.
- Check for rust, particularly on boat trailers and anything used near salt or fertiliser.
- Look for signs of repair: fresh welds, patch plates or new paint over one area.
- Check the deck, floor or body for rot, soft spots or damage.

- Tyres. Check tread, cracking, uneven wear (which can indicate alignment or axle problems) and the date codes.
- Wheel bearings. Spin each wheel and listen for roughness; check for play by rocking the wheel.
- Suspension. Look for broken leaves, worn bushes and sagging.
- Brakes. Check they work and, on electric or air systems, that everything connects properly.
Coupling and electrics
- Check the coupling, kingpin or turntable for wear and secure mounting.
- Test every light with the trailer connected.
- Look for damaged wiring, corroded plugs and dodgy repairs.
- Check safety chains, breakaway systems and jacks or landing legs.
Heavy trailers: for semi-trailers, tippers, tankers and low loaders, consider a professional inspection. Hidden chassis damage or a worn turntable can cost far more than the inspection.
What lenders care about
Lenders want confidence that the trailer exists, matches its paperwork, is clear of other finance and is worth what you're paying. Having your PPSR search, photos and the VIN details ready makes approval faster. If you're buying privately, read our private sale finance guide too.
