So the time has come and I hear a bearing in my drive belt it's not as happy as it used to be. I'm doing some research it appears that some people used the same pulley for the 3 different positions. When I had all mine off i noticed one of my pulleys the bolt wasn't able to be removed and appeared that changing the bearing wouldn't be so easy. I don't recall what the exact differences were. The weird thing is the one to the left which is the different one I accidentally installed in a different position than it was. and 1 of the 2 that i accidentally installed in the left position was not happy and it rang like a church bell. I can't find any info of this to confirm this. has anyone heard of this? cause if im going in im going all the way changing all of them especially after im gonna have to unhook that god awful motor mount thanks!
