A while back these was a post about a tech bullitin from GM that had to deal with the front end knock in Eldos/Sevilles 95-02. I did a search and can't find it, can someone give me a link? There was something about putting foam in between two parts.

Yeah, I remember reading that also. Do a search on "swaybar" I think. The repair was to place friction tape between the frame bracket and mounting surface of the bushing bracket that is bolted to the frame. Apparently this bracket moves forward and backward as it wears in. I remember seeing the drawing in the service bulletin web page and the description.
