Did you notice the words between the 2 little curvy things? In most cases would mean there are some that don't have these issues. Read some of the 100's of posts on this forum about the problems others are having. A properly shimmed diff will last a good long time but, the tranny is junk without a serious upgrade. A UE Super 6 and top shaft will do the trick but, the stock Revo/3.3 tranny is pretty good to start with.
