About a month ago I was driving through some snow that we had and I put the x in 4wd to get through a bad side street. I didn't know at the time that I had to go in reverse to release the hubs when I was done, so I didn't. I heard this awful noise, went to the dealer, and they said my hubs wern't unlocked. They also said that it wont mess up the hubs at all. Well, I looked at them that night and there was these dents all around the black things in the middle of the hubs. Now, the black covering that was on the black thing in the middle of the front passanger hub is....not so black anymore. It looks like the black coating was ripped off from when I didnt go in reverse. Can I just leave it like this or do I need to bring it in to be fixed? Would this be covered under warranty (my x is still covered)?
