In my experience, the most frequent reason for the phenomenon I term the "St. Vitus Dance" is -as belga1 points out- a slight imbalance in the contact points for the three wheelsets: center (nose or tail), left and right main.It is a real challenge to configure contact points that will work properly in FS9 and FSX. Most often it simply can NOT be done, which is why it is necessary for the developer to test extensively in both sims if they are releasing separate versions for each.
