Brake Adjustment and Air Leaks
Slack adjusters out of spec, cracked air lines, and leaking glad hands are some of the most common calls we get, especially on trailers that sit through cold snaps and then get pulled hard on Highway 43.
Flat Decks, Grain Trailers & Lowbeds
Mobile Trailer Repair in Grande Prairie
A dead trailer at a grain elevator or a gravel pit off Highway 40 doesn't just cost you time, it can shut down a whole run when the tractor is stuck idle behind it. Northern Mobile Repair sends a service truck to wherever the trailer sits, whether that's a yard in the Richmond industrial area, a lease road near a gas plant, or the shoulder of Highway 43 with hazards on. We work on highway vans, flat decks, super-B grain and gravel combinations, lowbeds, and tridem axle groups, so we're used to the range of gear that actually moves freight and equipment around the Peace Country.
Trailer problems tend to show up at the worst time, usually loaded and usually far from a shop. We carry the parts and tools to handle most brake, wiring, bearing and suspension failures on site, and if a repair needs a shop's lift or specialized equipment, we'll tell you straight up instead of pretending we can fix it on the shoulder. Our goal is to get the trailer legal and rolling again, or get it parked safely so the load and the driver aren't sitting in the ditch waiting on a tow that costs more than the fix would have.
Common Trailer Problems We See
Wheel Bearing and Hub Failure
A growling or smoking hub on a super-B or flat deck usually means a bearing is starting to go. Left alone it can take out a spindle or drop a wheel, so we check and repack or replace on site when we can.
Electrical and Lighting Faults
Chafed harnesses, corroded pigtails and blown ABS modules are a constant issue on gravel road running near Bezanson and out toward the gas plants, where dust and moisture get into every connector.
Suspension and Air Ride Issues
Broken air bags, cracked hangers, and worn bushings show up more on trailers that spend time on county gravel and lease roads rather than pavement, and they can throw an axle out of alignment fast.
Landing Gear and Coupling Problems
Bent or seized landing gear, worn kingpins, and fifth wheel plate wear cause coupling issues that leave a trailer stranded at a yard or job site until it's addressed.
Tire and Wheel Damage
Sidewall cuts from gravel pit debris, mismatched dual tires, and loose wheel bearings on lowbeds hauling heavy equipment are frequent calls, particularly during spring when road conditions are rougher.
Signs Your Trailer Needs a Look
- ABS or brake warning light staying lit on the tractor dash
- Uneven brake application or the trailer pulling to one side
- Grinding, humming or knocking noise from a wheel end
- Visible smoke or heat coming from a hub after driving
- Air pressure dropping faster than normal when parked
- Trailer lights flickering, dim, or not working at all
- Excessive bounce or sway that wasn't there before
- Difficulty coupling or uncoupling from the fifth wheel

Trailer Repair FAQs
Do you work on super-B grain and gravel trailers?
Yes, super-B combinations are common calls for us, especially during grain hauling and gravel hauling seasons around Grande Prairie.
Can you fix a trailer that's still loaded?
In most cases yes, particularly for brake, electrical and bearing work, though a fully loaded trailer with a structural or suspension issue may need to be unloaded first for safety.
What if my trailer is on a gas plant lease road?
We regularly dispatch to lease roads and oilfield sites around Grande Prairie, just let us know the access requirements when you call.
Do spring road bans affect service trucks reaching me?
Spring road bans can limit weight and routing, and we plan around them when dispatching, so let us know your exact location so we can route accordingly.
Can you handle lowbed and equipment trailer repairs?
Yes, lowbeds and tridem equipment haulers are part of our regular work, including suspension, brakes and hydraulic tail issues.
What if the repair is beyond what a mobile truck can do?
We'll tell you honestly if the trailer needs shop equipment like a full lift or frame work, rather than attempting something that won't hold up on the road.
