24/7 on-site repair across 20+ states. We come to your truck, roadside or in the yard, and finish most repairs on the spot.
A down semi is lost revenue by the hour. Missed appointments, detention charges, and freight that is not moving all stack up while the truck sits. All Fleet Inc. keeps 18-wheelers and big rigs rolling with 24/7 semi truck repair, both at our shops and on-site wherever you break down. Our diesel technicians dispatch straight to your tractor, roadside or in the yard, and finish most repairs on the spot. We operate 24 hours a day, 365 days a year, across a network that spans 20+ states.
Call now for 24/7 semi truck repair, shop or mobile.
Whether you bring the tractor to one of our shops or we bring the shop to you, we handle the full range of heavy-duty repair on Class 8 trucks and every major engine, from Cummins and Detroit to Paccar, Volvo, and Mack. Our technicians are heavy-duty specialists who work on commercial trucks every day, not a general garage taking the occasional rig.
Most breakdowns do not need a tow. Our service trucks roll fully stocked with diagnostic scanners, tools, and the common parts that put trucks back on the road, so the majority of semi repairs get done right where you are stopped, on the shoulder, at a dock, or in a lot.
When you call, our dispatch gets the essentials fast: where the truck is, what it is doing, the make and engine, and whether the driver is with the rig. That lets us send the nearest technician with the right parts already loaded instead of making a second trip. On arrival, the tech pulls fault codes from the ECM, diagnoses the actual root cause rather than just the warning light, and completes the repair on-site whenever the job allows. For a big rig hauling time-sensitive freight, an on-site repair in an hour beats a tow-and-shop scenario that can burn a full day. One call, one tech, one truck back on the road.
Emissions and aftertreatment problems are one of the most common reasons a modern semi ends up sidelined, and they rarely fail out of nowhere. The earliest warning sign is regens happening more often than normal. A healthy truck runs an active regen roughly every 300 to 500 miles. If it is regening far more than that, the DPF is loading with soot faster than it can burn off, usually because of long idling, short routes that never reach regen temperature, a failing sensor, or an upstream turbo or fuel issue.
Left alone, a clogging DPF forces the ECM to cut engine power, and a fully clogged filter drops the truck into limp mode, where it will run but not pull, which is dangerous on grades. Our technicians pull the codes, run a proper forced regen where the truck qualifies for one, and just as important, find and fix the root cause so the derate does not come right back. A forced regen typically takes 30 to 60 minutes in a safe location, and we carry the diagnostic equipment to do it at your truck.
A semi's air system runs the brakes, and small problems here become out-of-service violations fast. A hissing sound points to an air leak or a bad valve, and slow air build-up or reduced braking power means the system is not holding pressure the way it should. One of the most overlooked causes is the air dryer: when the cartridge is worn out, moisture gets into the lines and tanks, corroding valves in warm weather and freezing lines in the cold, which can lead to outright brake failure. We handle air leaks, chambers, slack adjusters, dryers, and full brake work, at the shop or roadside, and we can catch these issues on a preventive inspection before they strand a driver.
When a job calls for a bay, All Fleet operates staffed shops across our coverage footprint, backed by the same technicians and parts network that run our mobile units. From routine preventive maintenance and DOT inspections to major engine and driveline work, we keep your fleet road-legal and running without tying up your own yard.
Most expensive breakdowns start as small deferred-maintenance items catching up at the worst possible time. A PM program that tracks regen frequency, drains air tanks, checks fluids, and inspects brakes and tires on a schedule is the cheapest downtime insurance a fleet can buy.
Call it a semi, a big rig, an 18-wheeler, or a tractor-trailer, we work on all of it, every day. That focus means faster diagnosis, the right parts on the truck, and a repair that holds up on the next long haul. Our technicians know the failure patterns on each major engine platform, so they are troubleshooting from experience, not guessing.
We run like the carriers we serve, with fast dispatch, real technicians in our own trucks, and accountability you can reach by name. In freight, a truck sitting still is the most expensive truck you own. Getting the right tech to it quickly, shop or roadside, is the whole job. That is what we do.
One call gets a semi truck technician working on your rig, 24/7, shop or mobile, anywhere in our coverage area.
We run mobile truck and trailer repair across 20+ states. Find on-site diesel service in these metro areas and the surrounding 100-mile coverage radius:
Yes. That is the whole point of mobile service. Our diesel technicians dispatch directly to your breakdown, whether you are on the shoulder of the interstate, at a dock, or parked in your yard. Most repairs are completed on-site so you never need a tow.
We dispatch 24 hours a day, 365 days a year, and send the nearest available technician. For time-sensitive freight, an on-site repair usually beats waiting hours for a tow and then more time in a shop queue.
Our trucks roll fully stocked to handle diesel engine diagnostics, air brake and brake work, mobile tire service, DPF and DEF service and forced regens, electrical and no-start issues, trailer repair, and reefer diagnostics. Most jobs a shop bay handles, we handle at your location.
Yes. We cover tractors and trailers, including lights, liftgates, landing gear, doors, brakes, suspension, and refrigeration units. One call covers the whole unit.
