Most trailers need a full trailer service at least once a year, plus a quick inspection before every trip. How much more attention yours needs depends on how heavily it's used, how far it travels, and the conditions it operates in.
Key takeaways:
Most trailers need a full trailer service at least once a year, in addition to a quick inspection before every major trip. Wheel bearings typically need cleaning, inspecting, and repacking with fresh grease every 12 months or 12,000 kilometres, whichever comes first. Brakes, tires, lights, the coupler, and the electrical connections should all be checked at the same time. Trailers that haul heavy loads, travel long distances, or sit through a winter of salted roads often need service more than once a year to stay safe and reliable.
Minimum service schedule for most trailers:
These figures are general guidelines rather than a fixed rule for every trailer. A single axle utility trailer used a few times a season can often go a full year between services with no issues. A tandem axle equipment trailer hauling skid steers five days a week needs a closer look far more often, since heat, load, and mileage all accelerate wear on the same components.
What changes that schedule: several factors push a trailer's service interval shorter or longer than the yearly minimum, including how often it is used, how heavy the loads are, how far and fast it is towed, whether it is stored outdoors or under cover, exposure to winter road salt, and the trailer type.
Usage frequency matters because bearings and seals rely on grease that breaks down over time, whether the trailer moves or not. Load weight matters because heavier cargo puts more strain on axles, tires, brakes, and suspension components on every single trip. Distance and speed matter because highway towing generates more heat in the wheel hubs than short trips around town.
Storage conditions and climate also play a large role. A trailer stored outdoors through an Alberta winter is exposed to more moisture, temperature swings, and road salt than one kept in a heated shop, which can accelerate rust on the frame and corrosion in the wiring. Trailers with additional systems, such as the hydraulic lift on a dump trailer or tilt deck, need those systems checked on top of the standard mechanical items.
Some warning signs mean a trailer needs attention before its next scheduled service, regardless of when that appointment is booked. Catching these early is usually far less expensive than waiting for a component to fail on the road.
Watch for these warning signs:
Any one of these signs is worth a prompt inspection rather than waiting. A trailer that sways or pulls to one side while towing, for example, can point to a failing wheel bearing, uneven tire pressure, or a suspension issue, and continuing to tow in that condition raises the risk of a more serious failure.
A routine trailer service is built around the components that see the most stress: bearings, brakes, tires, lights, and the connection points between the trailer and the tow vehicle. Consistently checking the same items at every visit is what keeps small issues from turning into breakdowns.
A typical trailer service includes:
Certain trailer types add extra items to the list. Dump and tilt trailers need their hydraulic hoses, fittings, and fluid levels inspected, and any trailer with brakes should have those brakes checked against Alberta's trailer brake requirements at every visit. If you are unsure which parts on your trailer are due for attention, our guide to common trailer parts to replace and when breaks down typical replacement intervals component by component, and commercial trailer owners in Alberta should also confirm their CVIP inspection requirements alongside routine service.

If it has been close to a year since your last inspection, or if any of the warning signs above sound familiar, booking a trailer service appointment is the next step.
Most trailers should receive a full service at least once a year, along with a quick inspection before every major trip. Wheel bearings typically need repacking every 12 months or 12,000 kilometres, whichever comes first, and brakes, tires, lights, and the coupler should be checked at the same visit. Trailers that haul heavy loads, travel long distances, or operate through winter road salt often need service more than once a year.
Wheel bearings generally need to be cleaned, inspected, and repacked with fresh grease every 12 months or 12,000 kilometres, whichever comes first. Trailers that sit in storage for long periods, tow heavy loads, or are driven through water may need bearing service more often, since both moisture and heat accelerate wear on the bearings and seals.
Yes. Trailers that sit unused for long stretches still need an annual service, since tires, seals, and wheel bearings can deteriorate from age and inactivity even without heavy use. A pre-trip inspection is also worthwhile before the first trip of the season, since components can dry out, corrode, or seize while the trailer is parked.
Skipping routine maintenance allows small issues, such as worn brake pads, dry wheel bearings, or corroded wiring, to develop into larger failures. This can lead to reduced towing safety, roadside breakdowns, and repair bills that are often higher than the cost of routine service would have been. Regular maintenance also helps protect a trailer's resale value.
Signs that a trailer's brakes need inspection include longer stopping distances, a grinding or squealing noise, uneven braking side to side, or a burning smell after towing. Trailer brakes should be inspected at every scheduled service, and sooner if any of these signs appear.
