These are crazy issues!! I think mine is the front wheel because when I swapped out the wheel, the noise miraculously went away...
I stopped by the LBS to pick up some grease(Don't have left at my house) and he greased it it up for me

. I will see how it works today. If anything I will just use that other wheel until I bring it back. I can't stand riding when I hear all these noises, they bother me and I end up wasting the ride trying to figure out whats going on!!
I have to buy some grease though, seems to be useful for many of these issues
I had an issue with the seat too, the seat would loosen just a bit to start creaking. I carry my mini tool and tighten the bolt every couple hundred miles to make it go away.
Fun times
