Mobile Semi Truck Diesel Repair

Fast response for breakdowns, no-start conditions, derates and on-site diagnostics. This service is built for the real world. Shoulder calls, parking lot calls, job site calls and “we have to get moving again” calls.

No-Start and Hard-Start Diagnostics

Troubleshooting fuel, electrical, air, and sensor-related starting issues. We test and verify the cause so you are not throwing parts at a problem. Common issues include low voltage, failing starters, fuel priming problems, sensor faults and air system complications.

Accurate diagnosis of derates, warning lights and performance-related faults

Advanced computer diagnostics, fault code analysis and mechanical engine repairs. Whether it is a drivability issue, misfire, loss of power or a more serious mechanical concern, we start with a proper diagnosis and explain the repair plan clearly.

Radiators, hoses, water pumps, thermostats, fan clutches, belts and pressure-related issues. Overheating can take a truck out fast and cause major engine damage. We track down leaks, pressure problems, cooling flow issues and component failures.

Injectors, injection pumps, lift pumps, fuel priming problems and fuel leak repairs. Fuel delivery issues show up as hard starts, stalling, rough idle, low power and erratic performance. We diagnose supply versus high-pressure side issues and repair what is actually failing.

Batteries, alternators, starters, wiring issues, parasitic draws and electrical fault troubleshooting. Electrical problems are often intermittent and frustrating. We focus on testing, confirming voltage drop, finding the real failure point and restoring reliability.

Air compressors, air leaks, valves and air-related braking system issues. Low air pressure and air leaks can shut you down. We locate leaks, repair air system problems and address components that are preventing proper air build and brake function.

U-joints, driveshafts, carrier bearings, wheel bearings, seals and vibration-related driveline issues. If you have vibration under load, clunks on takeoff, bearing noise or leaks around seals, we diagnose the driveline components and repair the source of the problem.

Complete removal and replacement of transmissions and clutches for trucks and equipment. When an R and R is needed, we walk you through the scope, timeline and the smartest path forward to reduce downtime.

Diagnosis and repair of DPF issues, regen failures, derates and aftertreatment system problems. If your truck will not complete a regen, keeps derating or is throwing aftertreatment faults, we diagnose the root cause and repair it correctly.

NOx sensors, pressure sensors, temperature sensors and related components. Sensors fail, wiring fails and sometimes the issue is not the sensor at all. We confirm the failure before replacement to avoid repeat problems.

EGR-related components and emissions system repairs. We perform emissions system repairs correctly. No deletes.

Diagnosis and repair of DPF issues, regen failures, derates and aftertreatment system problems.

Scheduled maintenance designed to reduce downtime and prevent costly failures. Preventative maintenance is the difference between planned service and a roadside shutdown. We help fleets, owner operators and equipment owners stay ahead of breakdowns with service that fits your schedule.

Diagnostics and repair of cab air conditioning problems such as warm air, weak airflow, cycling issues, refrigerant leaks and component failures, with testing-based repairs that restore proper cooling performance.
