This is actually a scheduled maintenance interval. its called the mid life rebuild. At 15,000hrs, The engine , torque, tranny and axles components are replaced with exchange. Along with power train hoses and driveshafts. Then back to work for another 15,000 hrs and then machine gets a complete rebuild. Wiring, hoses, center hitch bearings, computers, etc.
The reason for a mid life is not push components to point of failure and lose value in the core component. Cheaper to refresh an engine than to wait for it to throw a rod out the block or replace a differential before housing and main structure items are damaged.
Long story short.....preventative maintenance.
