I ordered and received the balancer this week. I just had a shop install it for me - it was easier that way. The mechanic tells me the sound is gone and the old balancer fell apart on him. I haven't picked it up yet, but will get it after work. He assures me all is well though.
Thanks for the information and getting me headed in the right direction! I have been going through withdrawl while waiting for the part, so I can drive again.
