I'm about ready for a fresh rear gear and had been planning on using a Torsen (got a used Miata unit sitting in the garage), but lately I've been hearing reports that they're not durable. Anybody have any real info on how long these things last? A source I believe to be reliable says don't expect more than 2 years.

Thanks,
