2024 Kenworth T680

Category, Trucks. Mileage profile, 464,170 miles indicates a highway-duty life with the usual long-haul wear points, driveline lash, suspension bushings, wheel-end seals, and cooling system seepage being the areas that typically show first at this interval. Paperwork identifiers include VIN 1XKYD49X1RJ361120 and stock 0633594 for service history matching. Powertrain data, engine, transmission, axle ratio, and ECM details are not provided, so the evaluation hinges on verification steps, ECM hours, idle percentage, aftertreatment history, and any active or stored fault codes. ECM readout matters here, it is the quickest way to confirm duty cycle, regen frequency, and whether the mileage aligns with engine hours. Frame rails, look for straightness at the rear suspension hangers and around the fifth wheel area, plus any added holes, cracks, or corrosion at crossmember junctions. Fifth wheel, check top plate wear, slider rail condition, and air line routing for chafe. Cab and sleeper, inspect seat base play, pedal wear versus stated miles, HVAC performance, bunk hardware, and any dash warning lamps, then confirm tire match, brake lining depth, and steer axle kingpin play during a front-end shake test.
