Maintenance & Inspections
A PM service is a scheduled inspection and maintenance visit that covers fluids, filters, brakes, tires, and other key systems, designed to catch small problems before they become costly breakdowns. We recommend scheduling PM service every 10,000-15,000 miles, though the right interval can vary based on your truck’s duty cycle and mileage. Staying on schedule helps extend the life of major components and reduces unplanned downtime.
Our DOT inspections cover the full checklist required for compliance, including lights, brakes, tires, and suspension. We identify any issues that could affect safety or compliance and often complete necessary repairs during the same visit. This helps keep your truck or trailer legally on the road and avoids the cost of a failed inspection down the line.
Yes, we use advanced computer diagnostic tools to quickly and accurately identify issues in diesel engines and other truck systems. This lets us pinpoint the exact cause of a problem, from engine performance issues to electrical faults, rather than relying on guesswork. Faster, more accurate diagnostics mean less time in the shop and lower repair costs overall.
Yes, our DEF service includes a full system flush, a sensor check, and a refill to keep your Diesel Exhaust Fluid system operating properly. A failing DEF system can trigger a check engine light, reduce fuel efficiency, or force your truck into derate mode, so catching issues early matters. We diagnose and resolve DEF-related problems to avoid unnecessary power loss or downtime.
Trailer & Suspension
Yes, we repair and service trailer suspension components, including air-ride systems, leaf springs, shocks, and bushings, as well as full trailer brake service. That covers everything from brake pad and drum replacement to brake adjustment and air system checks. Keeping both systems in good condition is essential for safe handling and stopping distance, especially under heavy loads.
Common warning signs include uneven tire wear, a noticeably rougher ride, the truck pulling to one side, or visible leaks or damage around shocks and air bags. Unusual noises over bumps or a bottoming-out feeling are also signs worth checking. If you notice any of these, it’s worth having the suspension inspected before it leads to bigger, more expensive issues.
Pulling to one side is most often caused by wheel misalignment, uneven tire pressure or wear, or a worn suspension component. Brake issues, such as a sticking caliper, can also cause this symptom. Our alignment and suspension inspections can pinpoint the exact cause and correct it, rather than just treating the symptom.
Yes, we provide truck and trailer alignment services to correct pulling, uneven tire wear, and handling problems. Proper alignment extends tire life and improves fuel efficiency in addition to making the vehicle safer to drive.
A leaking wheel seal is usually caused by normal wear, physical damage, or improper installation. Left unaddressed, it can lead to lubricant loss and serious hub or bearing damage, turning a small repair into a much bigger one. We diagnose and replace failing wheel seals early to prevent downstream damage.
Engine & Structural
The most common warning signs include visible smoke from the exhaust, engine overheating, unusual noises, or a noticeable loss of power. A check engine light or reduced fuel efficiency can also point to an underlying engine issue. If you notice any of these, our engine diagnostics can identify the specific cause before it leads to a more serious failure.
Reefer repair covers the maintenance and repair of refrigerated trailer units, the cooling systems that keep temperature-sensitive cargo, such as food and pharmaceuticals, safe in transit. This includes diagnosing refrigeration unit failures, repairing compressors and cooling components, and performing routine maintenance to prevent mid-route breakdowns. A failed reefer unit can mean lost cargo, so fast, reliable repair matters.
Yes, our welding services cover structural repairs, framework, and trailer body damage for both trucks and trailers. This includes everything from crack repairs to custom modifications, handled in-house by our own technicians rather than outsourced. Structural integrity is critical for safety, so we treat welding repairs with the same care as any major mechanical work.
Yes, we provide full brake replacement services for heavy-duty trucks and trailers, including brake pads, drums, brake switch replacement, and emergency brake cable replacement. Whether you need a routine brake change or a more complex repair, we handle the full range of brake system work. Properly functioning brakes are one of the most critical safety systems on a commercial vehicle, so we don’t cut corners here.
A belt tensioner typically lasts tens of thousands of miles, though the exact lifespan depends on usage, engine type, and driving conditions. Watch for strange engine noises, squealing or rattling sounds, or visible belt slippage, as these are the clearest signs that the tensioner is starting to fail. Replacing it promptly when these symptoms appear helps avoid a sudden belt failure, which can leave you stranded.
