So, I have a '94 XJ 4.0L 5-speed. D30 HP in front, 8.25 in rear, and 3" lift. One of my hubs recently went bad, after listening to the howling for a couple of weeks, I got two new hubs and replaced them this weekend. But like a week before I changed to the new hubs, my front end felt really loose. Kind of like when your tires are really low, and it feels a little drifty (if that's a word). The only thing that has changed was the hubs. any ideas on where to start? I have tried to shake all steering components by hand, and everything feels tight. The D30 is out of a '96, I did the 4WD conversion this past summer. I put in all new ball joints, and I replaced one of the TRE about 2 months ago. So, I'm kind of lost right now.... I do have a drop pitman arm that I have not installed yet, do you guys think this may be the beginning of bump steer?

Thanks,
J
