ASE-certified diesel technicians with OEM diagnostic tools dispatched to your location. On-site commercial truck repair across the Charlotte metro area and I-85 corridor.
When your truck goes down, towing a Class 8 vehicle to a shop costs time and money you don't have. CTR's mobile truck repair service dispatches ASE-certified diesel technicians directly to your location — whether that's a highway shoulder, truck stop, fleet yard, or job site.
Our mobile units carry OEM-level diagnostic platforms (Cummins INSITE, Detroit DDDL, PACCAR Davie4), professional tools, common replacement parts, and fluids. We diagnose and repair on-site whenever possible — and when a repair requires shop-level equipment, we provide a written estimate and arrange towing to our Armentrout Drive facility.
Backed by 30+ years of heavy-duty diesel experience and the full resources of CTR's shop when needed. Call for same-day dispatch availability.

We confirm technician availability and provide an estimated arrival time. Call for same-day dispatch availability.
Our technician arrives with OEM diagnostic tools, assesses the problem, and provides a written estimate before any work begins.
If repairable on-site, we fix it and get you rolling. If shop equipment is needed, we arrange towing to our Armentrout Drive facility.
Some repairs require heavy-duty lifts, alignment racks, or engine hoists that can't travel in a service truck. When that's the case, our Armentrout Drive facility has everything needed for complete diesel engine, transmission, and drivetrain work.
On-site diagnostic fees apply toward the total repair cost when we tow to our shop. No double-charging for diagnosis. One team, one repair, one invoice.
