Vibration from front of car during deceleration...

[Club Cheetah]

So,

Recently I've been noticing a few incidents of vibrating coming from the front end. I've found maybe two or three times this happens more regularly.

First is backing out of the drive way. I have the car lowered and as I come out I often teeter on two or three wheels until I'm out of the driveway. This happens cause I don't want to scrape the front end. I have often heard a "grinding" sound from the front which I have attributed to the car having one of the front wheels off the ground.

Second time was coming off the highway. Nothing crazy but maybe going from 45ish to 20 or so. I had a feeling like the front wheels were loose. Which they weren't.

Third time was last night. Low speed in a parking lot going from 20 to about 5 mph. Same vibrating feeling.

Car is a 2007 S4 with 33,xxx. All work is up to date through a Audi dealership without issues. It has 19" wheels with Stasis CO which has never had any issues.

I'm due for a service soon and I will have them look over the front for this problem although I can't really reproduce the vibration yet.

Any thoughts?

Decel, meaning off throttle or while braking? If it's during braking, could be warped rotors. If not, maybe a loose control arm???

I thought the same thing with the rotors but its not consistant like i think it would be if it was the rotors. I'll turn them and see if that helps.

sounds like control arm bushings or possibly rotors
