Just had to replace a Campy Veloce rear derailleur after only 14k miles due to excessive play in lower pivot. Derailleur had been kept clean, lubricated, never crashed, etc. 14k miles seems a bit early to me -- what do you Campy experts think?
I have Ultegra on other bikes and have never had to replace a derailleur for other than crash damage; one of 'em has over 22k miles and is still tight as new, though on its third set of pulleys.

The only chronic ill I have had to address w/campy rds is IMHO premature pulley bushing wear. I prefer to use Tacx sealed bearing pulleys as they outlast campy 4X. Tom

well, i presume that by lower pivot you mean the lower pivot _bolt_. The other possibility is the pivot pins for the parallelogram. i believe that the thing that eventualy wore out in nuovo record derailleurs was the brass pivot pins holding the parallelogram together. when these got loose, shifting became very sloppy.
Did you ever take off the derailleur to see if the pivot bolt was properly set up to begin with (e.g. not too loose)?? A bolt that was not tight to begin with might wear out prematurely.
with campy stuff, you are not really supposed to replace whole units - just get out the catalogue (www.campagnolo.com) and find the pivot bolt in the catalogue, and order it through your bike shop. it will cost you maybe half the cost of a new derailleur, but then you're back in business without wasting a derailleur.
i am no expert in this, but i have heard that using smaller sprockets (front, rear) increases chain tension. is it possible that you were using smaller sprockets on the back because the campy equipment is just a whole lot faster than the Ultegra stuff ?? har.
