    You had better pop the cover and check those gears. After popping the cover turn the wheels and listen for any subtile grinding. Could be the bearings too....just too hard to tell without being there and looking at it

    Well, from my understanding, is that it needs to be shimmed correctly... not too sure what that means, but that is what I was told... which is why I didn't do my own... (hopefully I didn't get taken for a ride) /forums/images/graemlins/confused.gif /forums/images/graemlins/k5.gif

    <font color="green"> You were told correctly, but "it needs to be shimmed correctly" is the oversimplification of the year. You can learn the basics of how gears get set up here. </font>
