A system for testing a damping module includes a test machine configured to test a damping module, and a control module in communication with the test machine. The control module is configured to create an engineered input based on vehicle data, activate the test machine to test the damping module, provide the created engineered input to the test machine to simulate the vehicle data on the damping module while the test machine is testing the damping module, and receive, from the test machine, an output response of the damping module based on the engineered input. Other examples systems and methods for testing a damping module are also disclosed.

A door hinge assembly pivotably mounts a vehicle door member to a body structure member. The assembly includes a first hinge strap mounted to one of the members and having a vertical opening. A second hinge strap is mounted to the other member and has a spherical concave surface. A hinge pin is interposed between the hinge straps. The hinge pin has a portion received by the vertical opening of the first hinge strap. The hinge pin has a spherical convex surface for engaging the concave surface of the second hinge strap allowing variance in relative orientation of the hinge pin to the second hinge strap. The hinge pin is rotatably retained to one of the hinge straps allowing pivotable movement between the members. A removable retention bolt is carried between the hinge pin and the other hinge strap for retaining the hinge pin to the other hinge strap. The retention bolt allows removable retention of the door member to the body structure member. The concave and convex surfaces allow for variance in relative orientation of the hinge pin to the second hinge strap.
