In the front area of my D90 just behind the rad, I started hearing squeeking sounds that corresponds to the belts spinning. Belts are fairly new so I'm thinking bearings? I read somewhere that spraying teflon lube (like ones used on bikes) can quiet things down a bit. Can someone confirm that please? Also, if they are indeed bearings, can someone point me to a part #?
BTW, this only happens when it's raining. On dry days, all is quiet.. (well, quiet in D90 terms
