This joint does nothing but isolate road vibration. You can take off the old one and replace it with any copied rubber side wall from an old tire if you can't find a replacement. Look in the ditch of any road. I keep an old tire in my "outside storage area" and it is full of cut out replacement fixes. The city periodically totes off my cut up tire and it returns the next week....Russ __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
