I do not think that it is quite the same problem as the Toyota trucks and the Durango/Dakota trucks are having. When the ball joints go bad on these IFS trucks the wheel assemble falls off. I have heard nothing worse than sloppy steering on the Ram HD problems. Don't get me wrong, I think that either joints are poorly designed, but it is not the same safety problem. There was a thread on here about a month ago about a Toyota that had the front tire/wheel assemble fall off at highway speeds. A good friend of mine had a wheel/tire assemble fall off while checking cows. Thankfully he was only going 2 or 3 MPH.
I just ordered ball joints and need to get them installed. They have been bad for some time, but the tires have worn very evenly inspite of the bad ball joints. The joints on my Y2K are still fairly tight at 215K while my 2004 joints were loose at 50K and are now shot at 100K.
