Incorrect spindle nut torque could cause repeated failures of a front hub assembly. This could be a result of under/overtightening of the spindle nut, damage or excessive wear on the CV joint spindle threads, or damage/wear/loss of torque from reusing the original spindle nut instead of replacing it with a new one.
