Luckily its a metal pulley, so the bearing only can be replaced, $8.
The idler pulley is made from plastic, so its a throw away. I replaced that with a metal version ($33) as a precaution and i can replace the bearing only if it ever fails.
The next free moment i had i went back to the dealer, walked straight up to the service manger who served me. Cut straight in front of the customer he was attending to and slammed the bearing on the desk. He looked at me, i looked at the bearing, he looked at the bearing, i walked out.
Hours later i received a call of apology.
It was the most meaningless apology i have ever heard.
