Those #+%^ engineers!

A lot of the repairs being kinda crazy, is what components and groups of components are installed first at factory. Everything that goes on, can come off, but it certainly takes time/money/effort.

The sealed components, honestly, they probably have fewer engine failures with "lifetime" oil in a lawn mower (homeowner grade), then when it had a drain plug to vibrate loose, threads to leak, ect. Kinda like sealed u-joints; on average, they last way longer than greaseable, cause nobody is greasing them anyways.

Any u joint I replace usually has to be special ordered cuz I insist on greaseable u joints. Never once had a greaseable u joint fail. Like you said though nobody greased them except for a few folks like me. Iwas happy to see GMC still had greaseable ball joints and tye rods til at least 2018. Unsure on my new 2026 1/2 ton though. It doesn't even have a transmission dipstick unfortunately.

Having worked as an engineer in a defense industry, I know something about this. The problem wasn't the design, it was the inflexible standards and the procurement process. If an item needed 4 bolts we had to require full material certification and traceability. Eventually we made some progress in being able to buy larger quantities to maintain in stock but many things are one of a kind.

Just retired from 40 plus years in the defense industry - also making many one of a kind type things.

What KennyG has posted is the tip of the iceberg so to speak. Kenny mentioned just one of perhaps several hundred mandatory requirements added on over the past decades. These requirements permeate not just the supply chain, but quality, HR, facility, IT (especially), security, export, all aspects of manufacturing. Every function, every department, each have ten to twenty boilerplate provisions embedded into military contracts. Many have been for the good, many have absolutely no value to the product or process; all of them add to the cost of doing business.

Companies that can navigate and comply have a decided advantage over those that might have to take exceptions. These successful companies in turn, charge not just to cover the increased cost of doing business, but also for being the ones who can comply.

The high cost of these military goods are mainly the government's fault for enabling it to happen.
