2022 Kenworth T680

Category, Trucks. Mileage profile, 454,400 miles points to a highway duty cycle with steady run time, the kind of usage that typically shows up as driveline lash, suspension bushing wear, and aerodynamic trim scuffs rather than heavy vocational frame stress. Serial 1XKYD49XXNJ100255 and stock 0632806 give a clean reference for service history, recalls, and any OEM campaign lookups. Powertrain, engine, transmission, and axle ratio are not provided, so the practical next step is verification by build sheet and a road test focused on shift quality, cruise pull, and engine brake response. ECM data is listed blank, so an ECM pull matters here, look for total engine hours, idle hours, fault history, aftertreatment efficiency counters, and any evidence of recent parameter changes. Frame rails, inspect for straightness at the rear suspension hangers and around the fifth wheel mounting area, plus any added holes or heat marks from prior accessory installs. Fifth wheel, check top plate wear, slide operation, and air line routing for chafe. Cab interior, expect normal seat bolster wear and switchgear shine at this mileage, confirm HVAC performance, bunk functions, and any water intrusion at door seals and sleeper pass-through. Tires and brakes, measure remaining tread and match across positions, verify rotor and drum condition, and confirm ABS lamp behavior with a key cycle and a short roll test.
