Would anyone know what else squeaks in a 300tdi fan belt tensioner apart from the bearing? Whenever I replace a bearing the squeal never goes away. Only a new tensioner sorts it and this really drives me round the bend especially since so many posts on the internet stare that a replacement beseing is a cheap and easy fix. Yes it is cheap and easy (quick too - did today's job in under 10 minutes... the tensioner had a regular circlip rather than one of those nasty snap rings) but it never works for me hence I end up buying new tensioner just the same
