Drivers window makes a clunking sound when rolling up..

I have a 2010 taco w/106k miles on it. My drivers window started making a "clunking "sound when I rolll up my window. It seems to make the sound when the window is rolling up at about 1/3rd the way up ,then makes the sound again about 2/3rds the way up? It doesn't seem to have any problem goingup or down , but I'm sure this is the beginning of a problem down the road...any help or advice would be apprecited!

 

get some silicone spray and lube the rubber where the window goes up and down. its dry causing the sound

 

Tried the silicon spray , no dice..sounds kinda like a broken tooth in a gear? It doesn't make the sound rollingit down just up?
