Knoxville Truck & Trailer Repair – Mobile Diesel Mechanic – Knoxville, TN

Knoxville Truck & Trailer Repair sends certified diesel mechanics to your location anywhere in Knox County. We work on semis, box trucks, fleet vehicles, and heavy equipment without requiring a tow. If your rig broke down somewhere in East Tennessee and the Great Smoky Mountains region, we come to it.

Knoxville sits where I-40 and I-75 cross, making it one of the highest volume truck traffic intersections in the eastern United States. Pilot Flying J is headquartered here. The Smoky Mountains tourism corridor (Sevierville, Pigeon Forge, Gatlinburg) generates constant delivery truck traffic on US-441. Oak Ridge National Laboratory and Y-12 create specialized heavy hauling needs. When your truck goes down near Pilot Travel Center on I-40/I-75 (HQ city) or stalls on I-40, every hour offline costs real money. We move fast because downtime is expensive. Call for a free estimate with no tow required.

    About Knoxville Truck & Trailer Repair

    Most mobile truck repair companies want you to call a tow truck first. We built Knoxville Truck & Trailer Repair around the opposite idea. Your truck stopped somewhere in East Tennessee and the Great Smoky Mountains region and that is exactly where we come to fix it.

    Here is what you get when you call us:

    • A real mechanic on the phone who talks through what happened and gives an honest assessment before dispatching
    • A service truck stocked with common parts so we are not making multiple trips to fix one problem
    • Clear pricing before any work starts so you are not blindsided by the bill
    • Mechanics who work in East Tennessee and the Great Smoky Mountains region year round and know the terrain, the highways, and the weather patterns

    The Smoky Mountains create unpredictable weather patterns. Fog on I-40 through the mountains causes chain reaction accidents regularly. Mountain grades on I-75 heading into the Jellico Mountains burn out brakes and overheat engines. Winter ice on the mountain passes and summer thunderstorms make this a challenging corridor for trucks year round.

    We service commercial vehicles along I-40, I-75, I-81, I-640, I-275, US-441, US-129 and respond to breakdowns near Pilot Travel Center on I-40/I-75 (HQ city), Love’s Travel Stop in Lenoir City, TA Travel Center on I-81 in Morristown, Petro in Knoxville. When your rig stops moving in Knox County, we are the ones who come to it.

    • Slack adjuster service, ABS sensor troubleshooting, and brake adjustment

    Trailer Repairs

    Trailer problems stop a load just as effectively as engine problems. Landing gear failures, gladhand and brake line repairs, marker lights, door hinge and lock bar fixes, and reefer service.
