Mustang05

When i turn off my car after driving around there is this popping noise almost exactly every 11 seconds and it comes from the rear somewhat towards the gas tank/rear suspension.. and it just pops once ever 11 seconds i dont know for how long because i havnt stood there until its done because it just keeps on going but eventually quits.. does anyone else have this problem? Also there is some major creeking in the rear when i stop or go over bumps...anything on that? sounds kinda like a wooden boat in creeking.. its embarassing to tell you the truth..

first thing first ...that avatar is huge.down size it a bit......the sound you might be hearing is the exhaust...expanding a when it`s hot and contracting when it is cooling...as far as the creeking i would not know where to start....
