2022 Mack GRANITE

Category, Truck. Mileage profile points to a working vocational duty cycle, the kind of hours where chassis wear shows up in steer components, spring pins, and driveline joints sooner than a highway tractor. Dump application typically means frequent starts under load, short runs, and a lot of brake events, so service history and underbody condition matter more than cosmetics. Powertrain details are not provided, so verification should focus on engine family, transmission model, and axle ratio tags, then match that combo to the intended route speed and payload. ECM status is not listed, so confirm whether the truck has an accessible engine hours readout, active fault codes, and aftertreatment health data before putting it back into a daily cycle. Frame rails and crossmembers are the first stop on a dump chassis, look for flaking scale, fresh welds, and stress cracking around suspension hangers and any hoist or body mounts. Dump body, hoist pins, and hinge points should be checked for egg-shaped bores, loose bushings, and hydraulic seep at cylinder seals and hose crimps. Cab upholstery, pedal wear, and steering wheel shine are quick tells for operator hours, then finish with tires, brake lining thickness, and evidence of heat checking on drums or rotors.
