A turbocharger wheel balance-test jig including a base, a clamp mechanism, and an arm. The arm extends along an axis of rotation. The clamp mechanism includes an actuator actuatable between a locked position and an unlocked position, the locked position rigidly holding the arm with respect to the base. The clamp mechanism includes a stop configured to restrict rotation of the arm around the axis of rotation. In a method for acceptance testing an imbalance level of a turbocharger wheel, an imbalance level of the balance-test jig is measured, and subtracted from a plurality of measurements of a combined imbalance level of the turbocharger wheel balance-test jig and the turbocharger wheel. An estimated indicator of turbocharger wheel imbalance is then formed, and the turbocharger wheel is accepted or rejected based upon whether the estimated indicator of the turbocharger wheel imbalance is within an acceptable indicator range.
