I am hearing a light thumping sound when I hit over 60mph.. Its coming from the rear end not sure what it is. But it is loud and gets louder after 65. I'm not sure wtf it is but would like to know before I take it in and get it checked out. Anyone have any ideas?

 

check your tires could have a nail or some stone caught in it. also the tire could be bad. a steel belt inside could have slipped.

 

Ok, will do. That was my first thought was flat tire. And thinking damn now i have to use the even uglier spare lol. but they all seem to be ok on tire pressure. ill check
