Stud Pull-out Strength testing
Long service life and safety. The stud and housing strength need to be high enough to ensure long service life and safety of a part.
Best stud swing value. If the stud swing value is too low, the rod or other parts in the steering system may break.
Pullout strength. If the pullout strength is too low, the ball pin might be pulled out of the housing, resulting in the driver losing control of the vehicle.
Salt spray testing
