My '05 Grizzly has a very noisy front end which chatters mostly when going down hill (bumps). It seems to be better if I keep in the thottle some. I know some Grizzlys have front end chatter w/ slack in the shaft or something, but this seems more noisy than an '05 with 150 miles should be. Should I just run it and not worry, or spend some $ to have it looked at? I'm out of my 3 month warrentee I believe. Had I known how noisy the Grizzly can be I may have ended up w/ a KQ. Other than that I love it.
