I don't know about the rest of you, but everyone I know with a 2nd Gen. has what I would consider "premature" ball joint wear. I mean, needing replacment before 100,000 miles. Most, includung myself needed new ones by 60-70,000 miles. I was the only on with a winch bumper, everyone else was stock. So, in my mind, as long as you keep it within reason(less than 200lbs probably) I don't think the bumper effects the ball joints signifigantly. Thats just my opinion. Though, some of those Bid A** bumpers look guady though(Road Armor). I have seen some real sweet ones in my 4 Wheeler mags, but they all seem to be home/custom made. Of course, I would rather build it myself than buy it if it has to be fabbed/welded.
