Truck & Trailer Repairs We Perform
Commercial trucks experience constant wear from heavy loads, long hours, and demanding operating conditions. Our technicians diagnose problems quickly and perform the repairs needed to return your equipment to service safely.
Engine Diagnostics & Repair
Diesel engine problems range from minor performance issues to major mechanical failures that take trucks out of service. Our technicians diagnose engine concerns, identify the underlying cause, and complete repairs that restore reliable performance for commercial trucks and fleet vehicles.
Brake Systems
Commercial brake systems require regular inspection and maintenance to operate safely and remain compliant. We service air brake systems, chambers, slack adjusters, drums, rotors, valves, hoses, ABS components, and related brake hardware for trucks, trailers, buses, and commercial equipment.
Suspension, Steering & Front-End Repair
Suspension and steering components affect ride quality, vehicle control, tire wear, and overall safety. We repair kingpins, bushings, shocks, springs, steering components, front-end assemblies, and suspension systems for commercial trucks and trailers. Proper repairs improve handling and reduce unnecessary wear.
Drivetrain & Differential Repair
The drivetrain transfers power from the engine to the wheels, making it one of the most important systems on any commercial vehicle. Our technicians diagnose and repair driveshafts, U-joints, differentials, axle components, and related drivetrain systems to restore dependable performance and minimize downtime.
Electrical & Electronic Diagnostics
Electrical problems affect everything from starting and charging systems to lighting, sensors, and vehicle controls. Our technicians diagnose wiring issues, alternators, starters, batteries, lighting failures, and electronic faults to identify problems quickly and accurately.
Hydraulic System Repair
Hydraulic systems power many commercial trucks and specialized vehicles. We diagnose hydraulic leaks, damaged hoses, pumps, cylinders, valves, and related components to restore safe and reliable operation for equipment used in transportation, construction, and municipal applications.
Heating & Air Conditioning Repair
Driver comfort and visibility are important in every season. We diagnose and repair commercial truck heating and air conditioning systems, including compressors, condensers, blower motors, refrigerant leaks, and other HVAC components to help keep drivers comfortable year-round.
Welding & Fabrication
Some repairs require custom solutions rather than simple parts replacement. Our technicians perform welding and light fabrication to repair damaged components, reinforce equipment, and restore structural integrity when appropriate for commercial trucks, trailers, and fleet equipment.
Collision Repair
After a collision, our team evaluates accident damage and performs structural and body repairs needed to return trucks, trailers, buses, and commercial equipment to safe operating condition.
General Truck & Fleet Repairs
Not every repair fits neatly into one category. Columbia Fleet Service performs a wide range of general mechanical repairs, inspections, component replacements, and troubleshooting for commercial trucks, trailers, buses, and fleet vehicles. If your equipment isn't operating as it should, our technicians can diagnose the problem and recommend the right repair.

Mobile Repairs or Shop Repairs? We'll Help You Decide.
Many mechanical problems can be repaired where the truck is parked, saving time and avoiding unnecessary towing. Our dispatchers gather information about the problem before sending the appropriate technician or equipment.
If the repair can be completed safely on-site, our mobile diesel service trucks will perform the work at your location. When more extensive repairs are required, we can coordinate heavy-duty towing to our Jessup repair facility, where our technicians complete diagnostics, repairs, preventive maintenance, and inspections.
Working with one company from the initial breakdown through final repair helps simplify communication and reduce unnecessary downtime.
