How we create, verify, and update content to ensure every repair guide is safe, accurate, and shop-tested.
1. Who Writes Our Content
Every article on this site is written or technically reviewed by Alex Wealcher, an ASE Master Certified Heavy Truck Technician with over 18 years of field experience.
We do not use AI to generate repair procedures, and we do not hire generalist writers without mechanical backgrounds. If a topic requires specialized knowledge (like complex ECM diagnostics), it is handled directly by technicians with specific expertise in that system.
2. Our Verification Process
In the heavy-duty industry, a wrong torque spec or wiring diagram can cost thousands of dollars or cause safety hazards. That’s why we follow a strict workflow:
- Real-World Testing: Procedures are based on actual repairs performed in the shop, not just theoretical manuals.
- OEM Cross-Reference: All data (torque specs, fluid capacities, wiring pinouts) is double-checked against official OEM service manuals (Cummins, Detroit, Paccar, Volvo, etc.).
- Peer Review: Complex diagnostic flows are discussed with other master technicians to confirm reliability before publishing.
- No Guesswork: If we haven’t tested a fix ourselves or verified it through trusted industry sources, we don’t publish it.
3. Updates & Corrections
Diesel technology evolves, and Technical Service Bulletins (TSBs) come out often. We treat our articles as living documents:
- Last Updated Dates: Every article shows when it was last reviewed. If a procedure changes due to a new TSB, we update the content immediately and note the change.
- Reader Feedback: We actively monitor comments and emails. If a reader spots an error or has a better method, we investigate it within 48 hours. Valid corrections are made, and the contributor gets credit.
4. Sourcing & Independence
Independence: We are not sponsored by any truck manufacturer, parts supplier, or tool company. Our recommendations are based solely on what works best in the shop, not on affiliate commissions or brand deals.
Sources: When we cite technical data, we reference official OEM documentation, recognized industry standards (SAE, TMC), or verified field data. We avoid citing unverified forums or generic blogs as primary sources.
5. Safety First
Working on Class 8 vehicles involves high voltages, heavy components, and hazardous materials. Every guide includes specific safety warnings relevant to the task. We prioritize procedures that align with OSHA standards and manufacturer safety protocols.
