2022 Mack GRANITE

Duty cycle profile, 209,389 miles on a dump application points to mixed on road and jobsite time, with most wear typically showing up in steer axle components, driveline joints, brake hardware, and dump body hinge points rather than pure highway miles. Serial 1M2GR2GC5NM025245, stock 0630777. Powertrain details, engine, transmission, axle ratio, and any PTO or wet kit information are not provided, so application fit beyond general dump service cannot be matched to gearing or shift package. ECM hours and fault history are also not listed, so an evaluation should include an ECM pull to compare engine hours versus odometer, check for inactive codes, and confirm regen history if equipped with aftertreatment. Frame rails and front end, expect inspection focus on frame flange condition around suspension hangers and steering gear area, evidence of prior plow or push work, and any cracking at crossmember interfaces. Steering and suspension checks should include kingpins, tie rod ends, drag link, spring pins or air bag mounts depending on spec, and shock leakage, with a close look at tire wear patterns for alignment or bushing issues. Dump gear wear points, verify hoist cylinder rod condition, gland seepage, and pin and bushing play at the body hinges and hoist mounts. Body structure checks should include floor wave, side wall bowing, tailgate latch alignment, and any abrasion at the apron and cab guard, with attention to hydraulic hose routing, chafe points, and evidence of contamination in the hydraulic tank if present.
