I have a 2004 Lincoln LS Premium V8 and I love the car but it has been vibrating from the Driveline for a while now. I removed the driveshaft yesterday and the center support shaft bearing and the rubber is in good shape but the universal joint has a notchy spot in it. I am a mechanic and I know that the universal joint is not meant to be replaced. With that being said I cannot find a replacement driveshaft anywhere or even a listing on any Ford OEM Parts websites. What are other owners of Lincoln LS cars doing for replacements?
