Wierd sound coming fom my Driverside Drum

[2000 Silve GT-S]

I have this wierd sound coming from what I am pretty sure is my rear drum. Originally I would only hear it when I would break but now I hear it just during normal driving. Its hard to explain the sound but any suggestions? I'm going to get it checked out next Wednesday.

If its a tapping noise that gets louder when you drive by somthing (the sound bounces off passing cars) then its prob your wheel bearing.. I was having he same prob but toyota wants 300 to do it bucause you have to buy the whole assembley. They dont sell the bearing by its self...

Yeah thats what it sounds like. I'm going to take it into Toyota next Wednesday and hopefully since I still have my warrenty they'll replace it.
