Servicing and repairing a trailer
A trailer spends most of its life parked, which is exactly why it fails. Wheel bearings dry out, brake shoes seize, tyres age out with tread still on them and couplings wear. None of it is expensive to stay on top of. All of it is expensive to discover on the Kings Highway.
The parts that actually need attention
Wheel bearings
The most common roadside failure, and the most preventable. Bearings need cleaning, inspection and repacking on a schedule. Water is the enemy — a trailer backed into salt water at the coast needs it far more often than the calendar suggests.
Brakes
Override and electric brakes both wear, and both seize when a trailer sits. Electric systems add magnets, wiring and an in-car controller, each of which can fail quietly — you find out on the first hard stop.
Tyres
Trailer tyres age out. Rubber perishes on a trailer that barely moves, so plenty of tyres with good tread are well past safe. Check the load rating and the date, and do not forget the spare.
Coupling and safety chains
The coupling wears at the socket and the latch. Chains and shackles have to be rated for the trailer and in sound condition. Both are inspection items and both are cheap to replace.
Lights and wiring
Corroded earths and chafed looms cause most intermittent trailer lights. Adaptors between plug types are the other usual suspect. A sealed loom and LED lamps largely end the problem.
Springs, chassis and floor
Leaf springs sag and crack, and floors and rails corrode from the inside. Structural problems are found by looking underneath, which is why an annual inspection earns its keep.
Why a trailer specialist beats a general workshop
This is not a knock on car mechanics. It is a straightforward point about what a workshop is set up to do, and it makes a bigger difference on trailers than most people expect.
The parts are on the shelf
A trailer workshop stocks bearings, couplings, brake components, springs, lamps and axle parts because it fits them every day. A dealership or general workshop orders them in — so a job that should take an afternoon waits on a delivery, and your trailer sits there while it does.
They can make the part, not just fit it
A trailer is welded steel. A builder with a fabrication shop can cut out a damaged rail, straighten a drawbar or make a bracket that no longer exists. A workshop that only fits supplied components has to declare the same job unrepairable.
Trailer brakes are their own trade
Override couplings and electric brake systems have little in common with a car’s hydraulics, and the in-car controller has to be set up to match the trailer. It is specialised, routine work in a trailer shop and unusual work almost anywhere else.
They know how it was built
When the workshop that services your trailer is the one that built it, nobody is guessing at the axle rating, the wiring or what the chassis will take. Resort Trailers has maintained trailers it built decades ago — that history is the diagnostic.
They spot what an inspection will fail
Someone who looks under trailers all day sees the perished tyre, the sagged spring and the corroded rail before a registry inspector does — which is the cheap time to find them, not the week rego is due.
Load and towing advice comes free with it
How you load a trailer causes a good share of what wears out. A trailer specialist will tell you your ball weight is wrong or your bearings are failing because of how it sits — a conversation that rarely happens across a service desk.
Damaged, not finished
Trailers get written off far more often than they need to be. A welded steel structure can be cut and rebuilt, and doing so keeps the existing registration and identifying plate — which, as the registration page explains, is not a small thing.
Common repairs
Bent drawbars, damaged mudguards, cracked chassis rails, sagged or broken springs, worn couplings, rusted-through floors and rewires.
Modifications
Adding a cage, sides, a canopy, racks, tie-down points or a different ramp arrangement. Often cheaper than the second trailer you were about to buy.
Worth checking first
Before you replace a trailer, get the structure assessed. The paint may look terrible while the chassis is sound — or the reverse, which is the more important case to catch.
