OK I called lcengineering and they told me to call magnuson. Magnuson told me Alpine would never send them bearings and couldn't tell me what part numbers they were, as Alpine would ask for the entire nose to do it themselves. So they referred me to Eaton and I ended up getting an answering machine. Waiting for a call back....
Oh and Jonny, this just started happening late this summer (50,000 miles without noise). I know my intake gaskets now have a very small leak and causes low idle at startup, is it possible that it could have something to do with it? And this noise really only happens about 1 out of 10 startups and lasts until I drive a little or let it make the noise for 3-4 minutes.
