Well guys it appears that my rear drive shaft is out of phase approximately 45 degrees. It has been that way for a minimum of 300 miles, (long story) and I am finally noticing after drive line vibrations have gotten progressively worse. The atv has about 800 miles on it. My concern is, what damage could I be looking at from this mistake? The bike is still under warranty and I am going to be having a discussion with my local dealer. Long story short, either they installed it out of phase 300ish miles ago when making a repair under warranty, or it came from the factory like that, they didn’t catch the mistake, and they reinstalled it incorrectly. I’m kicking myself for not catching it when greasing, which has been done regularly. What would you guys look for regarding gearbox and rear diff damage? In other words "How screwed am I"?
