I think that sounds logical, the rubber mounts do tend to flex a bit when they start to wear. I cant see there being enough torque from just the belt to bend the shaft, but I guess weirder things have happened. Maybe the accessories got to spinning real fast, then the fan clutch kicked in and put the added strain on the shaft, I think either that or the fan hitting the shroud would explain the knock you heard.

Hey Surfsup! I had a similar problem. Started my car up one morning and heard the water pump pulley grinding the balancer. (underdrive pulleys) Not completely sure why it happened. Only thing i can figure is that the shaft must weaken and bend slightly under the pressure of the belt. If you notice the tensioner moves and RPMs increase putting more pressure on the accessories. Hope this helps.

P.S. I thought this was a forum for auto enthusiats looking for help with their cars, not an english class?

This is true. When people can make sense of what they are reading, they can help much easier and the whole process is just faster.
