2022 Mack GRANITE

Category, Truck, vocational dump chassis with 186,500 miles, mileage level points to steady work cycles where cab, hoist plumbing, and rear suspension wear show up before major corrosion issues. Serial 1M2GR2GC6NM025884, stock 0633118, used condition, ECM details not provided, so any engine family, hours, and fault history should be verified through a proper scan and printout. Powertrain, engine, transmission, axle ratio, and lockup strategy are unknown from the provided data, so application fit cannot be tied to gearing or shift logic. Duty use on a dump spec typically benefits from torque management and cooling capacity, so inspection should prioritize radiator and CAC condition, fan clutch operation, charge air boot integrity, and evidence of soot loading around clamps that can hint at boost leaks. Frame rails, look for straightness at the rear section and around any hoist or body mounts, plus drilled holes, added brackets, and heat marks that suggest prior modifications. Suspension and driveline, check walking beam or air-ride components for bushing play, torque rod wear, and driveline slip yoke movement, then verify carrier bearing condition if equipped. Cab interior, evaluate pedal wear, seat base looseness, HVAC performance, and dash warning history, these are quick indicators of how hard the truck has been cycled day to day. Hydraulics and dump interface, confirm PTO engagement behavior, pump noise, wetness at fittings, and hose chafe points along the frame, then inspect any visible hoist pins, body hinge points, and tailgate hardware for egged holes or fresh welds. Brakes and tires, measure lining thickness, check for uneven wear that can indicate slack adjuster or cam issues, and inspect wheel seals for seepage, especially on rears where dump work tends to load bearings and heat the hubs.
