Good Afternoon Chaps ,
My car started to make a knocking noice on the bottom left hand side of the engine , having my breakdown company out he told me it is the bearing in the pulley that is on its way out .
Googled everything possible to find out what size bearing it is , i would rather see if can find out what size it is instead of stripping it all down to remove it and have to look around for the bearing .
It is confirmed that it is the fan belt pre tensioner pulley .
