I have an 07 M8, and once in a while i get a sound like the track is rubbing up inside the tunnel. I have checked the track extensively and found no area that looks like its rubbing. I am starting to wonder if its the Diamond drive. Has anyone had similar issues, or a solution? How about has anyone pulled the DD out of an M8? Are they easy to work on? Take special tools?
I would appreciate any help I can get.
Thanks

How loose is the track? Is it just ratcheting?

I dont think that it is loose enough to ratchet, that was one of my first thoughts. It only seems to make the noise when im not under throttle but as i roll over a hill or a roller in the trail. Mostly when its a little off camber.

For anyone who is interested, I pulled the outer case off my DD found no unusual wear, but what I did find was that the anti ratchets would rub on the holes in the track if there were any side ways force acting on it..... (ie off camber over rollers and hills). And for anyone thinking about working on the DD, Pretty simple and straight forward. If its on an M you can get into it without pulling it all the way out.
