While I await the arrival of my new pulley I have attempted to see if I can alleviate this screech for now, as I am nervous the sucker will freeze up on me. I removed both idler pulleys and tried to find any crevice, opening, anything. On the backside there seems to be an inner groove that may or may not lead inside. I sprayed some light lubricant inside then wiped the pulleys off well with a towel. I put them both back in their original locations, turned the key and....screeches. No change. Its aggravating. I will drive her limited, but I still need to drive to work tomorrow and Monday (30 miles total). Hope it holds...
