About Our Heavy-Duty Trailer Repair Services
Integrity Fleet Services handles professional trailer repair for fleets and owner-operators. Our trailer shop repairs commercial trailers with brake, suspension, axle, electrical, wheel-end, structural, and body problems. Mobile trailer repair is also available for equipment that cannot easily make it to the shop.
More than 20 years of truck and trailer experience helps our team diagnose problems accurately and recommend repairs based on the trailer's condition. Our goal is to restore safe operation while limiting unnecessary downtime for your truck and trailer.
Commercial Trailer Repair Services
Heavy-duty trailers depend on several systems to carry weight, track correctly, brake safely, and protect cargo. A problem with one component can also create wear elsewhere, so our technicians inspect the affected system before determining what needs repair.
Our trailer repair and servicing capabilities include:
- Trailer Brake Repair: We inspect and repair air lines, brake chambers, slack adjusters, S-cams, friction components, and related brake hardware.
- Trailer Suspension Repair: Our team services air ride components, airbags, leaf springs, bushings, hangers, and suspension mounting hardware.
- Trailer Axle Repair: We inspect axle condition, mounting points, and related components when a trailer pulls, tracks poorly, or develops unusual tire wear.
- Wheel-End Repair: Service may include bearings, hubs, seals, and other wheel-end components showing wear or failure.
- Trailer Light Repair: We diagnose damaged wiring, connectors, marker lights, brake lights, turn signals, and other trailer electrical problems.
- Landing Gear Repair: Our technicians inspect landing gear that binds, will not raise or lower correctly, or shows mechanical damage.
- Trailer Door Repair: Service includes damaged hinges, latches, tracks, hardware, panels, and cargo access components.
Semi-Truck Trailer Parts and Component Repair
Many trailer problems start with a worn or damaged component rather than a failure of the entire system. Our technicians inspect semi-truck trailer parts that commonly affect braking, tracking, load stability, lighting, and safe operation.
Depending on the problem, repairs may involve brake hardware, suspension components, axle parts, wheel-end components, electrical connectors, lighting, landing gear, body hardware, or structural pieces. Identifying the failed component first helps avoid replacing parts that are still serviceable.
Trailer Servicing and Preventive Maintenance
Regular trailer servicing helps catch wear before it leads to larger repairs or unexpected downtime. Our technicians inspect high-wear components such as brakes, suspension, wheel ends, lighting, landing gear, tires, and structural areas for developing problems.
Scheduled service also gives fleets a chance to address maintenance items before trailers return to regular routes. If we find worn or damaged components, we can explain what needs attention and recommend the appropriate repair.
Signs Your Commercial Trailer Needs Repair
Trailer problems often show up through changes in braking, handling, lighting, tire wear, or structural condition. These symptoms can help operators catch a developing problem before it causes additional component damage.
- Trailer pulling to one side: Axle position, suspension wear, or tire condition may affect how the trailer tracks.
- Uneven trailer tire wear: Suspension, axle, wheel-end, or alignment-related problems may create irregular tread wear.
- Air leaking near the brakes: Damaged air lines, fittings, chambers, or other air-brake components may reduce braking performance.
- Trailer lights cutting in and out: Wiring, connectors, grounds, or damaged lighting components may cause intermittent electrical faults.
- Grinding or excessive wheel-end noise: Bearings, hubs, or other wheel-end components may need inspection.
- Trailer sitting unevenly: Damaged suspension components, airbags, leaf springs, or mounting hardware can affect ride height and stability.
- Landing gear becoming difficult to operate: Internal wear, damaged gearing, or bent components may keep the landing gear from operating normally.
Trailer Types We Service
Different trailer designs develop different wear patterns based on cargo, loading practices, mileage, road conditions, and operating weight. Our Conroe trailer repair team services several common commercial trailer types.
- Reefer Trailer Repair: We repair the trailer itself, including brakes, suspension, structural components, axles, wheel ends, and trailer bodies. We do not repair refrigeration units or reefer AC systems.

What causes a commercial trailer to pull or track incorrectly?
A trailer that pulls or tracks incorrectly may have axle alignment problems, suspension damage, worn components, or tire-related issues. Commercial trailer repair technicians can inspect axle position, suspension condition, tires, and related components to determine what is causing the trailer to track improperly behind the truck.
Why are my semi-trailer brakes not working properly?
Semi-trailer brake problems can develop from air leaks, damaged brake chambers, worn friction components, slack adjuster problems, or S-cam issues. A trailer brake repair inspection can evaluate the air brake system and wheel-end components to identify what is reducing braking performance before repairs are recommended.
Can damaged trailer suspension cause axle and tire problems?
Damaged or worn trailer suspension components can affect axle position, ride stability, and how tires contact the road. A heavy-duty trailer repair inspection can check leaf springs, air springs, bushings, mounting hardware, axles, and tire condition to determine whether suspension wear is contributing to other problems.

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.

Body Work
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.

Brake Repair
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 System Repair
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.

Diagnostics & Electrical Repair
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.

DOT Inspection
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.

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 System Repair
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.

HVAC Maintenance & Repair
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.

Oil & Fluid
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.

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.

Transmission & Clutch Repair
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.

Wheel & Tire Repair
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.
