Trailer Worn Parts Replacement
Heavy highway miles and tough weather quickly wear down critical trailer components like brake shoes, air bags, seals, bushings, and wheel bearings. Driving on worn parts can compromise the safety of your drivers and others, and it can damage surrounding components over time. Dieseltech stocks a wide range of high-quality OEM and aftermarket replacement parts at our Coquitlam shop. Our mechanics quickly swap out degraded components and restore trailers to optimal running condition.
Safety Inspection for Trailers
Commercial Vehicle Safety and Enforcement (CVSE) requires regular trailer inspections. In BC, most commercial trailers over 1,401 kg GVW need a valid inspection decal, not just the big ones. Dieseltech is a CVSE Designated Inspection Facility. We inspect brakes, air system, wheel ends, tires, suspension, lighting, coupling, and kingpins to the provincial standard. If we find a defect, we can repair it in the same visit and finish the inspection.
