I've been lurking for a while and just came acrossed something I thought I would share since I haven't seen anything posted on it. My AC idler pulley decided to lock up on me the other day totally shredding the belt. When I went to Autozone and Advance neither place had one. With little momma wanting her air back I went on the hunt. The "pulley" looked just like a bearing so I went to tractor supply and don't ya know it they had an identical bearing for like $6 and change. Thats a hell of a difference from the $30ish I have seen everywhere else. Its a 17mm bearing at TSC and if anyone wants I can get the exact part number.
