Yea, these U-joints suck. I have only 68k miles on mine and its got some "flat spots" in the U-joints. I brought it to a couple local custom driveshaft shops and they just told me to buy a new one. I mean, c'mon, you are a custom driveshaft shop, and you can't do custom work on this? Seriously, its not that hard once you have a machine shop available. There MUST be a U-joint of similar size in existence somewhere. I wouldn't mind coming up with some U-joint service "kits" to sell for a couple hundred bucks. They can be serviced if the parts exist

The thing that makes them go bad is that the grease in the joints has just dried up over the last 15 years and now it is corroded and and the joints are frozen. Simple as that. Not really a wear and tear item per say.
