As many of you know the hub on my cooling fan for the coach failed and the fan blades shattered and went flying around the engine compartment at a high rate of speed.  The radiator ,charge air cooler, and supporting brackets were damaged..  good news is the damage from fan flying around is covered by insurance but not the fan failure itself.. 

The main purpose is everyone check your cooling fan for any sort of wobble.  The results of flying fan blades is not pleasant..  Just trying to be helpful

Marc,

Did you notice any vibration or noise prior to the catastrophic failure?

Yes I did, probably 30 seconds before it felt like a the coach was going over a rumble strip on the side of the road . I slowed down and it went away. Then I noticed temp climbing.. Repair estimate not cheap.. It looks like the hub that the blades attached to failed..
