hmmm...that does seem a little wierd eh?

Look...it might be a couple of things. I have been told that the bearing mount often breaks and that could be the problem.

I will tell you exactly what I see...the fan is still intact and attatched to the clutch. The fan and clutch/pully as one unit are wobbly on the bearing mount. I took a look inside the hole that you posted, and cant seem to see a bolt, which is why I say it is missing. The tension of the belt is forcing it downward and the fan blades were rubbing against the pully below it, which is what caused me to notice.

Any help?
