First of all, Hello to the forum members,just recently registered and appreciate letting me join, Thank you. As I stated in my heading, I just bought this 1994 Suburban 2wd, it's starts great,but, the starter seems to my a loud whining noise while the starter is rolling the motor over, does it need a shim or could the starter be going bad ? Keep in mind I just bought it so I have no info on truck as far as the starters age. Thank you
