  • 2024 edition covers axles from 1982-onward — single doc spans the installed base; interval tables are the teaching core (what to inspect when, and wear limits).
  • Excellent companion (more tutorial, APAC-flavoured): Hendrickson Trailer Suspension Maintenance Manual 97117-161 Rev F — hendrickson-intl.com (108pp: wheel ends, S-cams, slack adjusters, brake chambers, ABS sensors, air springs, height-control valves, ride-height setting, TIREMAAX, tyre-wear diagnostics + alignment) — reads like a course.
