I can't feel any of the vibration any more. I think the problem was not adding the friction modifier - I know you're supposed to, but I didn't cause of what everyone says about using the royal purple, which is what I used. So I added the friction modifier (which, by the way made my garage permanently smell like ****) and now its running great with no rubbing sound or vibration.

 

Glad to hear it went away The modifyer smells great huh How much did you add one bottle?

 

ya, just one. made all the difference between with and without it.
