Hi all ive got a noise on my engine that sounds like a worn/rattling bearing ive had a quick look and the aux belt is the problem it seems to be boucing about flexing or flaping (this was silly to do but) if you put a something near the belt with the engine running you can feel the belt slapping, the tension of the belt seems fine it does not slip or anything like that, has anyone else had this problem ??
TIA

Hi markspark
Strongly suspect that it is the tensioner bearing that you are hearing. Does the belt squeal on full steering lock? On mine, it would  squeal on full lock, but made no sounds under normal driving. Tensioner can just about be  replaced without removing anything else, but it is a tight fit. My old one had quite a bit of wear both in the bearing and in  resistance to compression although  the tension of the belt appeared OK with the worn out tensioner. I guess the only way to prove it is to release the tension of the tensioner by unscrewing the retaining bolt and giving all the pulleys a  once over. If you do decide to replace it two things to bear in mind.
1) have a careful look at the new tensioner and identify the cast in (22mm?) nut on the body of the tensioner which is the means of getting the tensioner into a position where you can replace the belt (creating sufficient slack)
2) following an earlier crankshaft pulley failure, my tensioner fell off on start up due to its single fixing bolt shearing off about a week of use. I would strongly recommend that this bolt is replaced if disturbed.
 Hope my experiences help.
