Don't hold your breath Bob. The rational for returning worn parts (by statute in many states) is to assure that owners who PAID for parts actually get new parts ... because they returned the worn out parts to you. If it's a defect? You don't pay. The dealer does. They aint gona let go of stuff that might get put back into another vehicle. You may have better luck grabbing the CTS part from a salvage yard. Since it's what ... 1 out of 100 use? Even that would be a rare find. .
