February 15, 200619 yr The serve is just a collection of plastic cogs, it could be that they are wearing a it thin. try pulling on the cable fitting and see if it is 'sloppy' the other thing it could be is llose cables themselves, in which case it's time for about £20 on replacement parts. (Is there any kind of heat sheild that could have worked loose?
