Phil,
We've seen similar failures under similar driving conditions
due to no fault of the driver. The spider gears aren't
really designed to carry much of a load as they are designed
merely to handle the speed differential in turns. When you
couple a loaded truck, on a grade, making a turn, you have a
triple whammy of a load on the spider pinions and they
eventually fail.
In 42 years of doing exclusively transmission and drivetrain
work, I don't know of anything I would recommend in this
particular to prevent this from happening again except to
change the route the truck is driven. That's usually not an
option, so I simply replace the gears, explain the situation
to the customer, and send them down the road.
