I just watched video on phasing and angle...it was very informative...thanks!
this is the video I watched and I can tell you that the sound the card makes is very similar to pulsating vibration I get... since the driveshaft is new and in phase to itself...its gotta be the angles are off. man I never even thought about angles...I sure am glad for the help!
not sure how to get this video to link right...here is the link with a space before and after the be. delete the spaces.
