Moose Jaw Truck Repair and Maintenance FAQ

We recommend a full suspension and undercarriage inspection every 15,000 to 20,000 km for gravel-heavy drivers, or twice a year: once in spring (after winter salt) and once in fall (before winter). If you’re farming or driving grid roads daily, that’s closer to every 10,000 km. It’s a fast check that catches loose tie rods, worn ball joints, and shock leaks before they turn into steering or alignment problems.

In order of what we see in the shop: shocks (leaking or blown), tie rod ends (loose, causing steering wander), ball joints (worn, causing clunks), wheel bearings (humming or rumbling noise), and sway bar links (rattling over bumps). All of these are safety-critical and worth catching early. A failed ball joint at highway speed is a serious problem.

Yes. Standard paper filters clog quickly in prairie dust. We’ve pulled filters at 8,000 km that looked like a two-year-old filter from a city driver. For grid road drivers we recommend inspecting the filter every oil change and replacing it more frequently, or moving to a heavy-duty or oiled cotton filter (like K&N) that can be cleaned and reused. If your truck is running poorly, losing power, or getting worse fuel economy, a plugged air filter is one of the first things to check.

Trailer brakes and brake controller settings, tire pressure (truck and trailer, hot vs. cold matters), hitch and safety chains, trailer lights, wheel bearings on the trailer, and your truck’s coolant temperature and transmission fluid condition. For long tows we also recommend checking brake pad thickness before you leave. Towing eats brakes faster than any other driving condition.

It can, especially if the transmission runs hot. Modern trucks handle towing well, but transmission fluid degrades faster under load. If you tow regularly, we recommend transmission fluid service every 60,000 to 80,000 km rather than the ‘lifetime’ fill the manufacturer sometimes claims. A transmission cooler is a smart addition if you tow heavy loads or in mountains.

Sometimes. For occasional light towing (a small utility trailer or boat), stock pads are fine. For regular heavy towing (RV, horse trailer, equipment), a heavier-duty pad compound (severe-duty or towing-rated) will last longer and hold up to heat better. We’ll help you match the right pad to your actual use. No upsell on parts you don’t need.

Every 12,000 km or once a year, whichever comes first. Trailer wheel bearings are one of the most common causes of highway breakdowns. They run hot, they don’t get much maintenance attention, and they fail without warning. We repack bearings on utility trailers, RVs, and boat trailers. Bring the whole trailer or just the axles.

Yes. We service farm trucks all season long. Half-tons, three-quarter tons, one-tons, gas or diesel. We understand farm trucks get abused: they carry loads they weren’t designed for, sit for weeks between uses, get topped up with the wrong fluids, and come in with ‘this rattle’ or ‘that grinding noise’. We diagnose with a plan, fix what needs fixing, and tell you what can wait until next off-season.

Yes. We service Duramax, Cummins, and Power Stroke diesels for oil changes, brake work, suspension, exhaust, alignments, and general diagnostics. For deep engine internal work on modern diesels (injector timing, DPF regens that won’t clear, specialty tuning) we may refer you to a diesel specialist, but for most day-to-day repair and maintenance, we handle it in-house.

Once a year minimum, even if the kilometres are low. Oil breaks down over time from moisture, oxidation, and fuel contamination. A truck that sat all winter with 3,000 km on the oil is still due for a change in spring. Time-in-oil matters as much as distance.

Change the oil on time (or on the calendar, whichever comes first), keep tire pressure correct, and don’t ignore small noises. Most ‘sudden’ breakdowns on farm trucks aren’t sudden at all. The truck was telling the driver for weeks. Catching a wheel bearing hum or a shock leak early is a $400 fix. Waiting until the bearing seizes is a tow bill plus a $1,500 repair.

Yes. Passenger tires (P-metric) aren’t rated for the load a half-ton carries once you add a topper, gear, and a full box. Light truck tires (LT-metric) are built with stiffer sidewalls and higher load ratings. For most half-tons, especially with a canopy or if you tow, LT-metric tires are the right choice. We’ll help you match the right tire to your actual use.

For most drivers, a dedicated winter tire with the 3PMSF (three-peak mountain snowflake) rating in an LT size that matches your truck’s load rating. Popular options: BFGoodrich KO2 (winter-rated all-terrain), Michelin LTX Winter, Cooper Discoverer Rugged Trek, and Cooper Discoverer Road+Trail. All-weather tires (3PMSF-rated) are a decent option for trucks that see mixed use, but a dedicated winter is always safer at −30°C on ice. Call us for pricing on a full set.

Every second oil change, and always before winter. Trucks eat brakes faster than cars because they weigh more. A half-ton with a box full of gear puts a lot more energy through the brakes than a compact car. For daily drivers we usually see front pads needing replacement every 60,000 to 80,000 km; towing regularly shortens that significantly.

If it’s below −20°C, yes. We recommend it for any gas or diesel truck. A block heater warms the engine oil and coolant so the engine cranks easier, oil flows to the top end faster, and you’re not putting cold-start strain on the starter and battery. Diesel trucks especially benefit. Cold diesel fuel gels below −30°C and the engine simply won’t start reliably without a block heater. Two to four hours before you drive is plenty; overnight is fine but a timer saves electricity.

Three to five years for most trucks. That’s less than a car battery because trucks have higher electrical demands (bigger engine to crank, more accessories, sometimes dual batteries). Cold weather is hard on batteries; we recommend a battery test every fall to catch weak batteries before they leave you stranded at −30°C.

For any prairie highway drive in winter: tires (pressure and tread), fuel level (fill up before you leave; service stations are sparse), block heater cord tucked away, wiper fluid topped up with winter-rated fluid, and an emergency kit in the truck (blanket, boots, water, phone charger, jumper cables or booster pack).

If you’re within 1,000 to 2,000 km of your next oil change, yes, do it before the trip. Fresh oil handles heat and highway RPMs better than old oil, and you don’t want to be dealing with an oil change in an unfamiliar city.

A pre-trip inspection is a fast check of tires, brakes, fluids, belts, hoses, battery, lights, wipers, and suspension. We do them regularly for customers heading out on long drives. Call for pricing. It’s a small investment for peace of mind, and we’ve caught more than one issue before it stranded someone on the highway.
