Truck DOT Inspection Services in Texas, Louisiana, & Oklahoma

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.

Your heavy-duty vehicle’s body work is responsible for maintaining adequate aerodynamics, benefits your fuel efficiency, and protects your engine and other vital components. It also maintains the look and aesthetics of your vehicle! Here at Integrity Fleet Services, we offer an all-encompassing set of body services. Whether you got into an accident or simply want custom work, our highly trained bodywork professionals will get the job done. 

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.

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.

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.

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.

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 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.

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.

As an 18-wheeler operator, you’re expected to drive in all types of weather. Whether you’re driving through the hot southern states or the cold Canadian provinces, you need a fully functioning HVAC system to keep you comfortable and safe. Here at Integrity Fleet Services, we consider ourselves to be HVAC experts. We have tons of experience working on AC and heating systems, and hundreds of happy customers to match.

For your major components to work properly and last a long time, you need to perform preventative maintenance on a routine basis. This preventative maintenance starts with regular oil and fluid changes. Here at Integrity Fleet Services, we are preventative maintenance experts. We know the ins and outs of 18-wheelers better than anyone. We’ll have your oil and fluid maintenance done in a jiffy so you can get back out on the road.

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.

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.

18-wheeler operators drive hundreds of thousands of miles throughout their careers. They travel vast distances in all types of weather, in all climate types. Over time, drivers are bound to experience some sort of tire damage. The most common form is a tire blowout due to road debris. Here at Integrity Fleet Services, we offer a full suite of tire repair options. Whether you want your tire simply repair or completely replaced, our technicians have your back.
