Whether you have an existing preventive maintenance program or you need to develop one, our highly skilled and experienced DOT / FMCSA certified inspectors will take a hands-on approach to your fleet.

Integrity will build custom maintenance programs that best fit your specific operational needs and learn your field of service and operations to find solutions to all your fleet needs and challenges.

We can:

  • Build custom maintenance programs that fit specific operational needs
  • Carefully adhere to existing maintenance programs and protocols

Heavy-Duty Truck & Trailer repairs

Axle Repair

18-wheelers and other heavy-duty commercial vehicles require hefty axles in order to mitigate the strain of intense torque. Light-duty axles on a heavy-duty rig would likely snap, as the force they’d be under would be nearly unfathomable. Whether through age, use, or exposure to the elements, axles need to be serviced routinely. Here at Integrity Fleet Services, we consider ourselves to be axle experts. Our skilled technicians are well-equipped to handle any and all axle problems.

Heavy-duty commercial vehicles can carry or tow close to a hundred thousand pounds because of their powerful engine and strong drivetrain. Bringing a hundred thousand pounds to a stop requires a hefty amount of braking power, and as such, heavy-duty commercial rigs will generally have incredibly complex and powerful braking systems. Because of what heavy-duty air brakes do on a regular basis, they require significant repair and maintenance.

Coolant Systems

All vehicles that use an internal combustion engine will use some sort of coolant system. Heavy-duty coolant systems are usually a lot larger and a lot more complicated than what you’d normally find in a small or even medium-sized automobile. Ultra heavy-duty radiators and large coolant line systems are designed to handle an incredible amount of heat produced by large diesel engines. Heavy-duty trucks would catastrophically fail without their coolant system, so maintenance is mandatory.

DOT Compliant Inspections

If your heavy-duty commercial vehicle weighs more than 10,000 pounds, the US Department of Transportation requires you to obtain a DOT inspection certificate on an annual basis. Our technicians at Integrity Fleet Services can perform both State and Federal DOT compliant inspections. Besides ensuring your truck is safe and in peak operating shape, our DOT compliant inspection service will keep you fully compliant with the Department of Transportations rules and regulations.

Diagnostics & Electrical

Newer diesel models are full of electronics. They have a ton of sensors, huge computer units, and a crazy amount of wiring. This makes your diesel truck more prone to electrical issues. These issues can be quite complex, and often require hours' worth of troubleshooting. Computer diagnostic service is the process of connecting your equipment to our state-of-the-art diagnostic equipment and running tests. This allows us to quickly and accurately diagnose and repair your equipment the right way the first time.

Driveline Repair & Maintenance

Your driveline is responsible for taking your engine’s torque and transferring it to your wheels. This is typically done using a series of driveshafts and differentials. These components need to be maintained on a routine basis because replacing them altogether can be extremely expensive. One of the major component types in your driveline are your differentials. Your differentials take power from your driveshaft and transfer it to your drive axles. Here at Integrity Fleet Services, we offer an extensive selection of driveline repair and maintenance services.

Exhaust Systems

Exhaust systems are very important for heavy-duty 18-wheelers, for the bigger the engine, the more emissions. Alongside noise suppression, exhaust systems are also designed to protect the driver from harmful fumes and protect our atmosphere and environment. Using catalytic converters and other emissions control systems, your exhaust limits the amount of carbon that’s emitted into the atmosphere. Here at Integrity Fleet Services, we are exhaust experts.

Express Lube

If you want your heavy-duty commercial vehicle to last a long time, you need to perform adequate preventative maintenance. Here at Integrity Fleet Services, we offer a service called Express Lube. This service will ensure everything from 18-wheelers to lighter-duty haulers receives adequate maintenance in a proactive way. Our techs here at Integrity Fleet Services believe that proactive maintenance is far more beneficial to you as the driver than that reactive repairs.

Suspension Maintenance & Repair

Your suspension is an extremely important part of your 18-wheeler. Not only is it responsible for holding up extreme amounts of weight, but it’s also responsible for keeping you and your passengers safe. Unlike smaller cars, 18-wheelers use complex air suspension systems. These systems are designed to give you the strength of leaf spring setups and allow for comfort when not hauling. They can be complex, and as such, require routine maintenance and inspection.

Learn more

Transmission & Clutch

Your transmission and clutch are incredibly important. They allow your engine’s power to be transferred to your drivetrain using a variety of gears. These gears optimize your engine’s power input so you can haul extreme amounts of weight with relative ease. Here at Integrity Fleet Services, we’re experts at maintaining transmissions, but we are also fully equipped to do any and all transmission repairs that come our way.
