that is the question of the century which came first the chicken or the egg. The
stud was broken but was it the broken stud that caused the failure of the bearing or the bearing failure that broke the stud?
In my opinion as I stated in other threads is that the fact that the bearing was intended to be lifetime sealed with no oil feeding system and oil gets in washes out the grease but the oil breaks down because it does not get changed out. Imagine running the engine without an oil change for 30,40 or 50 thousand miles. All the bearings would fail for that same reason. Not to mention the lateral and torque stress factor on that bearing. This is an engineering bobo.
