FAQs
Keeping Columbia’s Heavy-Duty Fleets Moving Since 2013
Brakes
You should have a professional inspection every 25,000 miles or during every PM service to ensure DOT compliance and safety.
The leading causes are air leaks in the lines and out-of-adjustment slack adjusters, both of which significantly reduce stopping power.
Yes, we provide emergency roadside assistance for brake failures across the I-77, I-20, and I-26 corridors in South Carolina.
This usually indicates a faulty wheel speed sensor or an electrical issue in the ECU that requires immediate diagnostic tools to clear.
Yes. If oil or grease leaks onto the brake shoes, it ruins the friction material, requiring a full replacement of the shoes and the seal.
Tires
Yes, we provide fast roadside trailer tire repair services throughout South Carolina.
Absolutely. Our semi trailer tire repair team handles many repairs directly at your location.
Most mobile trailer tire repair jobs are completed within 30–60 minutes depending on damage severity.
Yes, if the tire is unsafe to repair, we offer replacement solutions.
Our technicians perform a full inspection and recommend the safest option.
Battery
Look for dimming headlights, a battery discharge warning, or unusual whining noises. Frequent "no-start" conditions after sitting often indicate the alternator isn't maintaining the battery bank's charge, or a cell has failed.
Diesel engines require massive cranking amps to turn over. Multiple batteries provide the necessary power and the reserve capacity needed for sleeper berth electronics and telematics.
Due to intense humidity and extreme temperatures, you should expect to perform a semi truck battery replacement every 3 to 4 years. High-wattage inverters can drop this lifespan to 2 years.
Yes. Our mobile units use specialized equipment to replace 60-70 lb batteries safely on highway shoulders, ensuring no "arcing" occurs that could damage the ECM.
Not necessarily. While batteries are common, a "no-start" can be caused by a failed starter solenoid, a blown high-amp fuse, or a faulty ignition switch circuit.
DPF Cleaning
Yes. Our mobile truck DPF service allows us to clean filters at your location.
Your truck may need a DPF filter cleaning if you notice:
- Check engine or DPF warning lights
- Loss of power under load
- Reduced fuel efficiency
- Smoke from the exhaust
- Frequent or failed regeneration cycles
Addressing these issues early prevents engine damage and costly repairs.
Most services are completed within a few hours, depending on truck type and filter condition.
Yes. Cleaning restores your filter at a lower cost while maintaining full functionality.
Absolutely. We provide truck DPF repair and evaluate all related emissions components.

Symptoms often overlap. We use precision diagnostics to determine if you need a full gearbox repair or a simpler fix like a clutch linkage adjustment or release bearing replacement.
Watch for Transmission Control Module (TCM) errors, overheating, burnt fluid smells, or internal slipping caused by the high torque of diesel engines.
Routine inspections identify metal shavings, seal leaks, or worn mounts early. This prevents catastrophic gearbox failure and maximizes your fleet uptime.
