It's my alternator. And maybe the tensioner bearing too - it seems a little rough. Alternator makes noise when spinning by hand. If I spin it by the shaft (using a spline tool) and it makes noise then it's likely the internal bearing and not the pulley? Am I correct? It makes noise when spinning by the pulley as well.
