Great, you found some web site that I already knew about. Problem is it doesn't lead to any conclusion that freewheel hubs or axles or hub bearings or whatever mechanical device you can come up with, had a higher failure rate then normal. These things (besides the front hub) was the MOST DEPENDABLE PART ON A BIKE!!!! You need to stop reading some site that shows that something broke; all mechanical things eventually break, that doesn't mean it's got a high failure rate. Like I said before, besides the front hub the rear hub and freewheel was and still is the second most dependable mechanical item on a bike.
