Is this for real? Does anyone have any updated specifics on this kit?

I called my local dealer and the person I spoke with in the service department claims they don't know anything about it (of course, they still act like my 2004 F150 Screw is the only truck they have seen with the rear end whining!). I would like to be able to go in with some specifics when I talk to the service manager.

They did tell me back in July 2004 that Ford was working on a fix.

Thanks.
