Since the weathers turned cold (last 2 weeks or so), I noticed my sentra 1.8 (2004) with about 22,000 km was making faint squeaking sounds when I wasn't acclerating (ie. makes noises when I first start it up, stopped at a stop sign, slowing down to stop, idling, etc). The sound seems to go away when I accelerate, and it sounds like I killed a mouse when I turn the engine off.

And now the last few days, the squeaking sound is really noticeable, to the point where I can here it constantly (but still goes away mostly when I accelerate)...

Anyone know what might be causing this? I think I know what it might be, but I'd be nice to get some confirmation...

i have no idea....i had the problem for about a week, and it seemed to happen when my brakes were wet....
