i finely get my truck running after 2 weeks (too long of a story). when i start it (good used starter) it makes one hell of a racket when cranking over. it its about 4x as loud as it should sound. i was told the starter was too far from the flexplate. is this correct? he said to put a half shim in it to rotate it closer to the flexplate. seems like it would work . ive never had this problem and have no idea what it could be. any help is apreciated.
