Why reliable mobile trailer repair matters
A disabled trailer is more than a mechanical inconvenience. It disrupts delivery schedules, triggers detention charges, and puts pressure on dispatchers, fleet managers, and drivers alike. When a breakdown happens far from a shop, the cost of towing adds up quickly, and waiting for a service appointment the following business day is not an option for time-sensitive freight.
Mobile trailer repair solves this problem by bringing the technician to the trailer. PH Fleet Services operates throughout the mid-Atlantic and Northeast, providing on-site repairs that get trailers rolling again without the cost and delay of a tow. Whether you operate a single truck or manage a regional fleet, having a reliable mobile repair partner in your contacts can mean the difference between a minor delay and a missed delivery.

Trailer types we service
Dry van trailer repair
Dry van trailers are the backbone of general freight operations, and keeping them operational is critical for on-time delivery. Common issues include damaged rear doors that won’t seal or open properly, roof damage from dock strikes or weather, faulty lighting and wiring, and air brake problems. PH Fleet Services handles structural and mechanical repairs on dry van trailers in the field, addressing the issues that most commonly pull units out of service.
Reefer trailer repair
Temperature-controlled trailers carry perishable freight, and a breakdown can mean a spoiled load in addition to downtime costs. Reefer trailers present unique challenges because both the refrigeration system and the trailer structure need to remain in working condition. PH Fleet Services addresses the trailer-side issues on reefer units, including electrical repairs, ABS system faults, air brake problems, seal replacements, and door repairs that can compromise temperature integrity.
Tank trailer repair
Tank trailers require careful attention during any repair due to the nature of the cargo they carry. Common field-serviceable issues on tank trailers include air brake problems, hose and fitting failures, electrical faults, and ABS system malfunctions. PH Fleet Services provides mobile repair support for tank trailer operators across our service area, addressing the mechanical and electrical issues that can take a unit out of compliance or out of service.
Trailer repair services
Air brake repair
Air brake problems are among the most serious issues a trailer can develop. Symptoms include slow brake application, spongy pedal feel, air leaks audible from the trailer, brakes dragging on one side, or a low-air warning that won’t clear. Air brake failures create compliance issues and safety risks, and most jurisdictions require trailers to be removed from service until the problem is corrected. PH Fleet Services diagnoses and repairs trailer air brake systems in the field, including brake chambers, slack adjusters, valves, and related components.
Brake lines
Damaged or deteriorated brake lines cause air pressure drops that affect braking performance across the entire trailer. Cracks, abrasion damage, connection failures, and fitting corrosion are common causes of brake line problems. A trailer with compromised brake lines should not be operated until the lines are repaired. Our technicians carry brake line materials and fittings to complete repairs on-site, restoring proper system pressure and function.
Hoses and fittings
Hoses and fittings connect critical air, fluid, and electrical systems throughout the trailer. A failed hose or loose fitting can disable air suspension, affect brake performance, or cause fluid leaks. These components wear over time and are especially vulnerable to damage during extreme weather or from road debris. PH Fleet Services carries a range of hoses and fittings to handle replacements in the field without waiting for a parts delivery.
Electrical repairs
Trailer electrical failures affect lighting, ABS systems, brake controllers, and reefer unit connections. Common symptoms include marker lights that won’t illuminate, brake lights that stay on or don’t respond, intermittent tail light failures, and fault codes related to electrical connections. Many roadside inspections cite lighting violations, which can result in out-of-service orders. Our technicians diagnose trailer wiring problems and complete electrical repairs on-site to bring trailers back into compliance.
Stuck tandems
Sliding tandem axles need to lock and release reliably for drivers to adjust axle position for legal weight distribution. When tandems seize or won’t slide, drivers are unable to reposition the axles, which can cause overweight axle violations or prevent a load from being legal to haul. Stuck tandems are often caused by dirt and rust buildup in the slide rail, damaged pins, or air lock problems. PH Fleet Services carries the equipment to free stuck tandems in the field so drivers can continue their trip.
Trailer door repair
Trailer doors take constant abuse from repeated loading and unloading, dock impacts, and weather. Problems include bent door frames, damaged hinges, worn seals that allow air and moisture into the cargo area, broken door cables on roll-up doors, and locking bars that won’t engage properly. A door that doesn’t seal or latch correctly creates cargo security and weather protection issues. PH Fleet Services performs trailer door repairs on-site, addressing both structural and hardware problems.
Trailer roof repair
Roof damage is a common and costly issue for dry van and reefer trailers. Dock overrides, low-clearance impacts, and weather damage can tear, crack, or puncture the trailer roof, allowing water to enter and damage freight. Even small roof openings can cause significant cargo damage on a single load. PH Fleet Services handles trailer roof repairs in the field, sealing damaged sections and restoring the trailer to weathertight condition.
Liftgate repair
Liftgates fail for a range of reasons including hydraulic leaks, motor failures, damaged platforms, worn or broken safety latches, and electrical problems. A liftgate that won’t operate strands a driver at a delivery stop without the ability to offload freight. PH Fleet Services diagnoses and repairs liftgates in the field, covering hydraulic, electrical, and mechanical components to restore full operation.
ABS repairs
Antilock braking system faults generate warning lights on the trailer and often result in out-of-service violations during roadside inspections. Common causes include wheel speed sensor failures, damaged wiring to ABS components, modulator valve problems, and ECU faults. ABS warning lights should never be ignored. PH Fleet Services diagnoses trailer ABS faults and performs the sensor, wiring, and component repairs needed to clear the warning and restore proper function.
Seal changes
Door seals, reefer seals, and body seals keep trailers weathertight and help maintain temperature integrity in refrigerated units. Worn, cracked, or torn seals allow outside air, moisture, and pests to enter the trailer, which can damage cargo and compromise reefer efficiency. Seal replacement is a routine maintenance item that is easy to overlook until the problem causes a cargo claim. PH Fleet Services replaces trailer seals in the field as part of both emergency repairs and scheduled service calls.
Common trailer problems we fix
The following issues represent some of the most frequent reasons operators contact PH Fleet Services for mobile trailer repair:
- Brake problems: air leaks, dragging brakes, weak stopping performance, and brake chamber failures that require immediate attention to keep trailers compliant and safe.
- Electrical failures: lighting violations are among the most common roadside inspection citations. Wiring faults, corroded connections, and failed components leave trailers out of compliance.
- Liftgate issues: hydraulic leaks, motor failure, and platform damage that prevent liftgates from operating, stranding drivers at delivery stops.
- Water leaks: roof damage, failed door seals, and body seam failures that allow water into the cargo area and cause freight damage.
- Door damage: bent frames, broken hinges, damaged latches, and worn seals that prevent doors from closing, sealing, or locking securely.
- ABS warning lights: sensor failures, wiring damage, and modulator problems that trigger warning lights and can result in out-of-service orders during roadside inspections.
- Stuck tandems: seized slide rails and stuck locking pins that prevent drivers from adjusting axle position for legal weight distribution.
