If the starter teeth were not aligned correctly with the flywheel teeth to "start" with,
then it may have caused premature bearing failure in the starter. Getting it just right with all the variables of flywheel and starter combos can be tricky.
But if you have a lot of miles on the install, this is an unlikely cause of the failure.
