DOUGLASSVILLE, PA · DRY VAN, REEFER & FLATBED TRAILER REPAIR

TRAILER REPAIR

The trailer takes as much abuse as the tractor pulling it — axles, brakes, doors, floors and wiring that keep freight moving and inspectors satisfied. Our ASE-certified technicians repair dry van, reefer, flatbed, lowboy and gooseneck trailers to DOT spec.

WHAT WE REPAIR

TRAILER SYSTEMS WE REPAIR

From the kingpin to the tail lights — trailer repair covers the whole unit, not just whatever’s obviously broken.

Trailer Axle & Suspension Repair

Axle alignment, hangers, bushings and air ride components specific to dry van, reefer, flatbed and lowboy trailers.

Trailer Brake Repair & Adjustment

Brake shoes, slack adjusters and ABS wiring on trailer axles, adjusted and repaired to DOT spec.

Trailer Electrical & Lighting Repair

7-pin connectors, ABS wiring, marker lights and brake lights — the electrical faults that get a trailer parked at inspection.

Door, Hinge & Latch Repair

Roll-up doors, swing doors, hinges, latches and seals that won't open, close or seal properly anymore.

Floor & Structural Repair

Soft spots, damaged crossmembers and frame welding on wood and aluminum trailer floors.

Landing Gear & Coupling Repair

Landing gear that's hard to crank, plus kingpin and upper coupler plate wear that affects hookup and towing safety.

A trailer sits outside, gets loaded and unloaded daily, and takes road vibration for hundreds of thousands of miles — it wears differently than the tractor, and it gets inspected just as strictly. At Fulmen Garage in Douglassville, PA, we repair the whole trailer: axles, brakes, electrical, doors and floor structure, on dry van, reefer, flatbed, lowboy and gooseneck units alike.

FAQ

TRAILER REPAIR QUESTIONS

We handle the trailer side of reefer units — structural, electrical, brakes, doors and floors — on dry van, reefer, flatbed, lowboy and gooseneck trailers alike. Refrigeration unit-specific repairs are coordinated as needed.

Most floor damage is localized — a section of crossmembers or a few damaged floorboards — and can be repaired without replacing the entire floor. A full replacement only comes up when the damage is spread across most of the trailer.

Repeated light failures usually point to a wiring or connector problem — corrosion at the 7-pin plug, a chafed harness, or a bad ground — rather than the bulbs themselves. We trace the circuit instead of just replacing bulbs one at a time.

Yes — drop trailers, yard trailers and units sitting between loads are common. Bring it in whenever it works for your schedule; it doesn’t need to be hooked to a tractor.

At every DOT inspection and PM interval at minimum, but trailers that see rough roads, heavy loads or sit outdoors for long stretches benefit from more frequent checks — axle and brake wear isn’t always obvious from a walk-around.

It depends entirely on the trailer and the damage — a light repair is a different job than a floor or frame repair. We inspect first and give you a clear, itemized estimate before any work starts.
