A loading assembly used in a vehicle spindle test fixture includes a wheel adapter housing that is mountable to a vehicle spindle. A pair of vertical struts are provided. Each vertical strut is joined to the wheel adapter housing at spaced-apart first pivot connections. A bell crank is coupled to each end of the vertical struts at spaced-apart second pivot connections. An actuator is pivotally coupled to the bell crank at a third pivot connection. The location of the second pivot connections relative to the third pivot connection approximates the location of the first pivot connections relative to the spindle axis.
