I replaced my stock starter with a new racing gear reduction starter. The old starter was noisy as compared to a new car that is very quiet.
My new starter is even louder than the stock one. Is there anything I can do to quiet down the sound?
All I have around the bottom of the fly wheel is a black plastic shroud. Is there any aftermarket full coverage shroud?
Most auto parts stores do carry the shims in the help section. But sometimes you do have to use half shims or shims on only 1 of the bolt holes. I can't remember for sure but putting shims on the inside bolt moves the starter away from the flywheel and putting them on the outside bolt moves it closer. I know Autozone used to give a little metal rod with their rebuilt starters to check the proper distance.
You may have to try several different combinations to get it right.
