So I was driving and then I heard a sound behind me like someone was letting air out of a tire. I figured it was coming from something that I was driving by however the sound followed me. (did get quieter tho)
Maybe im just being paranoid but when I got out I noticed me back end looks a little low. Nothing was rubbing so I drove 5 minutes the rest of the way home and the noise was gone by the time I got there. Im gonna upload some pics and see if you guys can confirm if something looks wrong or if its my imagination.

 

 

from the last pic everything looks ok,
