Posted November 17, 200717 yr Hey Folks Ive had the stethopscope around the belt pulleys etc today to try and locate a rummble/vibration and im almost sure its the top idler pulley thats suspect with a noisy bearing,is this a dealer part does anyone know. I also appreciate realistically that to change it the tension on the belt should be slackened off via the adjuster but just wondered if it could be done without going that far as would have to remove lots more parts futher down to get to the tensioner Thanks Paul
