Abstract: A test fixture for testing a motor vehicle suspension, brake components and wheel components on a motor vehicle sub-frame is provided. The test fixture can include a lower frame attached to a base surface and be dimensioned for the motor vehicle sub-frame to be attached thereto. An upper frame oppositely disposed to the lower frame and dimensioned to attach to the sub-frame is also included. A shaker system is attached to the base surface and is operable to provide a predetermined vertical displacement profile to the sub-frame. A motor is attached to an axle assembly on the sub-frame and is operable to rotate a wheel component at a predetermined rate of rotation. A non-contact gap sensor is included and can be attached to the sub-frame and detect or monitor movement between a first sub-frame component and a second sub-frame component.
