Did you have any trouble putting the axles back in? Usually if the housing is bent the axles are difficult to reinstall. I used to stand in front of mine and think the same thing. But is seemed like everytime I looked at it, it was bent a different way. It was just an optical illusion.
Check your allignment. Jack up the front end, and while resting a pen on a jackstand slowly spin the tire and draw a line all the way around it. Do that to both tires, then measure from line to line in front then behind. You should be 1/8 to 1/4" toe in, in front. Your tire wear could be just allignment.
If it is bent, I have heard that some places can straighten them, but it may be cheaper to find a used housing somewhere and just swap your parts over.
