Abstract: A hinge system includes a pillar hinge bracket connected to a door hinge bracket by a hinge pin. The pillar hinge bracket is secured to a vehicle body. The door hinge bracket is secured to a vehicle door. A checking device removably secured to the pillar hinge bracket and the door hinge bracket includes a spring portion and a pin portion. The spring portion biases the door hinge bracket to a first position and, in turn, the vehicle door to a fully open position. The pin portion has a first mounting post that secured to the pillar hinge bracket and a second mounting post that is received in an open-sided notch of the door hinge bracket. A ledge partially surrounding the second post includes a stepped portion to prevent unseating of the checking device as the door hinge bracket is caused to move relative to the pillar hinge bracket.
