I installed my bushing today. Success! Vibes are gone. I did notice them a little in the beginning of my test drive - very, very subtle. Then I couldn't notice them at the end of the drive. So I don't know if this bushing removes 100% of the vibes, but I'm really happy.
Also the driver's side CV shaft is solid now - it only moves just a little like the passenger side.
Check out my post in my build thread for a mini write-up and pictures.
