machining debris found in rear axle

So what you're saying is that you don't work at a vehicle OEM...

*My company just had 2 brand new international's go into full shutdown mode over sandblasting debris in oil passageways, on the way to delivering to the customer. They will be getting new engines.

Most oem's aren't machining to that level of precision

 

This really is a you problem. Most vehicles aren't spinning rotating assemblies beyond a few thousand RPM.

And the whole point of the magnet is to get most of the debris.

You're far better selling the truck and buying something like a Urus for more pristine manufacturing specifications

 

You are correct, not in automotive oem business.
Boat engine's.

 

Correct me if I’m wrong, but you’ve compared the machining tolerances and QA for manufacturing an engine to that of manufacturing a differential? Do you not recognize that the required tolerances are quite different between the two components, as are the likely impacts of debris left behind? Obviously proper quality control is vital for manufacturing of any component, but to directly compare the two is apples to oranges.

I performed my first diff oil change at around 35K and found machining residue on my magnet, and glitter in the oil. I’ve been changing it every 30K since. My diff is still in perfect condition at 115K. I wasn’t the least bit worried.

If I’d found debris in my engine oil after a change, that would’ve been a completely different story.
