Trailer Repair in Glendive, MT
Trailers take a beating and get less attention than the tractor pulling them. Mondak repairs van, flatbed, step-deck, tank, belly-dump and equipment trailers at the Glendive shop. Common work includes air and electric brakes, wiring and lights, air leaks, suspension, wheel bearings, seals and hubs, and structural repair through our welding and fabrication capability. Many trailer repairs are tied to inspection findings, so we can also fix what failed on a DOT inspection. Carriers moving along I-94 can plan a stop in Glendive to catch up on trailer work without a long detour.

THE MONDAK APPROACH
Diagnose first. Repair with purpose.
Trailer electrical problems are usually corrosion, so we follow the circuit instead of swapping lamps. Air problems get a leak-down check. Structural damage is assessed before welding to make sure a repair is sound.
Some trailer air leaks, lights and brake issues can be handled in the field where the trailer is parked. Wheel-end, suspension and structural repair belong in the Glendive shop.
