2022 Kenworth T680

Category, Trucks. Mileage history, 704,000 miles points to a highway duty cycle with the usual long haul wear pattern, driveline slack checks, cooling system seep points, and cab touch surfaces that show up after extended seat time. Serial number, 1XKYD49X8NJ484732; stock number, 0633116. Powertrain details, engine model, transmission, axle ratio, and any ECM data are not provided, so application fit and gearing comments should be based on a drivetrain ID pull and a road speed versus RPM check. ECM access matters at this mileage for idle hours, derate history, fault counts, aftertreatment performance, and last regen trends. Walkaround items, frame rails and crossmembers should be checked for corrosion at fasteners, elongated holes around suspension hangers, and any evidence of prior repairs. Fifth wheel top plate wear, slider rail condition, and air line routing are common inspection points, along with steer tire edge wear, brake chamber stroke, and air system leak down. Cab interior, sleeper upholstery, seat base play, HVAC output, window regulator function, and dash switchgear are the usual high use areas to verify before assigning remaining service life.
