So, I have finished my 2000 ss finally. I have had it for a year, finished putting the 97 front end on. My problem is that when i get at 2000 rpms, i get a little vibration.. nothing horriable, but i figure with only 3500 miles on it, it should not have a vib at all.. It does it at idle, or while running, so the only thing i can think of was the harmonic balancer, but to my eyes, it looks fine ( thought it may have been damageed in the accident) Does anyone else have any other suggestions? Thanks much

 

try taking the serpentine belt off and see if it still vibrates. you may have a bent pully on the alt or a/c or the tensioner.
