It is really interesting how some of these cars go well over a 100k without anything and others have issues. I decided to change mine because I didn't want to be driving in 100 degree weather 150 miles from home and it to go on me. Here are the pictures:

Mine was the original (still had the coating on it) and also looked new but the shaft had a very slight bit of play and that was enough to cause the squeal, it doesn't take much under the pressure of the serpentine belt to cause these to start making noise.
In 1990 I drove a 1966 Landrover from San Diego to Miami and just after I crossed the Florida state line I heard a noise and saw green fluid coming from the hood. I shut it off and coasted to the berm. When I opened the hood the fan was about an eighth of an inch from the radiator. The WP bearing had come completely off the shaft and the belt had pulled the shaft out of the housing. I got it shut off just before the fan and pulley destroyed the radiator. A local garage got it fixed the next morning and I was off to Miami. That was the worst case WP failure scenario I had seen.
