Semi Truck & Trailer Repair
A Full-Service Heavy Duty Truck Repair Shop
Some truck problems can be handled with roadside semi-truck service. Others need a shop, a lift, diagnostic equipment, or more extensive repair work.
Blue Gray Towing operates a full-service semi-truck and trailer repair shop in Hagerstown, MD, for work that requires in-shop service. Our heavy-duty diesel mechanic shop handles engine and transmission problems, brakes, steering and suspension, electrical issues, trailer repairs, welding and fabrication, preventive maintenance, and more. We work on trucks for local fleets and owner-operators as well as drivers who run into trouble while passing through the area.

Semi Truck Repair From the Engine to the Axles
A problem with the engine isn’t handled the same way as an air leak, steering issue, or worn suspension component. Our Hagerstown shop can diagnose and repair problems throughout the truck rather than limiting service to one or two systems.
Semi-truck repair services include:
If you aren’t sure what’s causing the problem, bring the truck in for diagnostics so we can identify the source before replacing parts that don’t need replacing.

Diesel Engine & Transmission Repair
Hard starting, oil leaks, loss of power, turbo problems, shifting issues, and other changes in how a truck runs can indicate problems with the engine, transmission, or supporting systems.
Blue Gray provides diesel engine and transmission diagnostics and repair at our Hagerstown shop. Our operators can also tow a disabled truck to the shop when it can’t be driven in safely.
Semi Truck Brake, Steering & Suspension Repair
A truck that doesn’t stop, steer, or handle the way it should needs attention before the problem gets worse. Blue Gray repairs the systems that keep heavy trucks controlled on the road, including brakes, air-brake components, steering, suspension, hubs, axles, and differentials.
Brake service can include work on pads, rotors, drums, brake lines, and air brake systems. Steering and suspension problems can also be diagnosed and repaired at our Hagerstown shop.

Trailer Repair & Fabrication
The tractor may be running perfectly while the trailer is what keeps the load from moving. Blue Gray repairs commercial trailers at our Hagerstown shop, including mechanical, electrical, structural, and access-related problems.
Trailer repair services include:
Welding and fabrication capabilities also give us options for trailer damage and component repairs that can’t be solved by simply replacing a standard part.
Preventive Maintenance for Semi Trucks & Trailers
Not every shop visit has to start with a breakdown. Routine maintenance gives drivers and fleets a chance to address wear, leaks, damaged components, and other issues before a truck is taken out of service.
Blue Gray provides semi-truck and trailer maintenance, including oil changes, fluid checks, belt and hose inspections, and other routine service. For fleets, scheduled maintenance also makes it easier to plan service around operations rather than waiting for a breakdown to take a truck off the road.


Fleet Truck & Trailer Repair
One truck in the shop affects a driver. Several trucks down at the same time can affect an entire operation. Blue Gray works with commercial fleets that need a local shop for ongoing maintenance and repairs, rather than having to find a new repair provider every time something goes wrong.
We can support fleet vehicles with preventive maintenance, diagnostics, mechanical repair, brake and suspension work, electrical repairs, trailer service, welding, and other shop work. Call us to discuss the trucks and trailers in your fleet, as well as the type of maintenance or repair support you need.
Truck Broke Down Before Getting to the Shop?
A truck doesn’t always give you the convenience of breaking down during shop hours or within driving distance of the repair facility. Blue Gray also provides 24/7 roadside semi-truck service, medium duty towing, and heavy duty towing throughout Western Maryland and South-Central Pennsylvania.
If the problem can be repaired where the truck is stopped, our roadside service may be able to get it moving without a tow. If it needs shop work, we can tow the truck or trailer to our Hagerstown facility.
