Noise from pulley possibly dur to poor lubrication

Three months ago, I bought a can of belt dresser and sprayed
quite some on both sides of the belt when the engine is running,
hoping this will make the belt run smoother and last longer.

Suspecting that the pulleys may be subject to crust or loss of lubricant,
I also sprayed the WD-40 around all the shafts of the pulleys.
After some days, I heard the rattle (click,click....or chirping) from
that region. Af first I doubted that this noise may be from the
notorious synchronizer. Now I am pretty sure that the noise is from
one of those pulleys. I worried if the WD-40 will wash away the
lubricating grease which is applied inside that rotating part when
the car is made. What grease or lubricant is good for use to
restore the lubrication of those pulleys if lost?

Thanks a lot

probably the tension pully and those need replacement every now and then for bad bearings.

It's either the idler pulley or the tensioner. The best way to find out is with a mechanic's stethoscope and make sure your mullet is tied back!

If it is the synchronizer assembly you can grab it by hand while engine is runnung and feel it grinding as it chirps. Take the belt off and spin the pulleys by hand and see if you can pinpoint the problem. Try starting it for a few seconds with the belt off and see if the noise is still present.

If you don't have a mullet, and want some fun, put on select pieces from your Home Shopping Network's Mr. T Gold Jewelry Bling Bling collection

Or a long screwdriver or a long extension.
