2019 International LT625

Duty cycle shows up in the odometer, 524,390 miles points to highway and regional linehaul use rather than short, stop and go work. Wear focus at this mileage belongs on steer tires, brakes, wheel seals, driveline U joints, and any coolant or charge air leaks that only show under sustained load. Powertrain details are not provided, so engine family, transmission type, and axle ratio cannot be tied to a specific application. ECM status is blank, so verify engine hours, idle percentage, fault history, and aftertreatment data by pulling an ECM report and comparing it to dash hours and service records. Frame rails and crossmembers should be checked for corrosion scaling, cracks around suspension hangers, and evidence of prior repairs or added holes. Fifth wheel condition matters here, look for top plate grooving, loose mounting bolts, slider rail wear, and air line routing that can chafe. Cab interior and sleeper hardware should be evaluated for high use items, seat base play, pedal wear, HVAC performance, bunk hinges, and any water intrusion at door seals or sleeper seams. Cooling stack cleanliness and CAC boots are common leak points on higher mile tractors, so inspect for oil misting, loose clamps, and rubbed through hoses before putting it back into steady pull work.
