I'm going look for an oem cv axle from pick n pull to replace the cheap Napa axle that's making my car vibrate. How do I tell if an axle is an oem? Is there a label that would not likely be worn off? I assume the vw part number would be stamped on it somewhere as well. What do I look for ? Also does anyone know what years would be compatible with a 2000 1.8t passat?
