If the truck had 75k on it when they bought it, who knows how the previous owner treated it.

I wonder if the previous owners let the engine idle down before shutting it off.
I always did that with my old 3.5 ecoboost and never had an issue.
You mention failed bearings.
They say you’re supposed to let the turbo cool down but I’ve always seen it as bad to shut the engine off when the turbos could be spinning at higher RPMs, how’s the oil supply to them after you shut it down if they’re still spinning fast ?
