I just replaced this same pulley three months ago! My wife was just driving and the whole pulley just snapped off! The replacement was hell getting into place (could not reach the bolt!) So now the same pulley is squealing really bad again as if it's going to let go again. I'm really worried as this is our only form of transportation at the moment. Is this a common problem? and is there any easier way to reach that bolt if I need to replace it again? Any help would be greatly apprecieated! Thanks in advance.
