Heavy Duty Truck Repair at the Roadside or the Yard
Heavy trucks fail differently than pickups. The loads are bigger, the air systems are safety critical, and a wheel end that runs hot at seventy is a far more serious problem than the same fault on a light vehicle. The repair has to match that reality.
We work Class 7 and Class 8 equipment on the shoulder, in yards and on job sites across the corridor. That covers tractors hauling freight, dump trucks working local jobs, and the vocational equipment that never sees an interstate but still has to run every day.

Signs You Need Us Now
Heavy Duty Faults That Cannot Wait
On equipment this heavy, a few of these are safety problems long before they are repair problems.
-
Wheel end running hot
A failing bearing or dragging brake that can seize or catch fire under load.
-
Air pressure dropping
A leak somewhere in the system, and the truck will not release until it is found.
-
Engine losing power on grades
Fuel restriction, a tired turbo, or aftertreatment forcing a derate.
-
Coolant disappearing
A heavy diesel that overheats twice can turn into an engine replacement.
-
Suspension sitting crooked
A failed airbag or broken spring throws weight where the frame never wanted it.
