Steering Oscillations

[Vincent Gelinas]

Hi, all! Patient is a 2004 A6qA with about 139k. 3.0 gas V6. 

Good news! My car passed inspection and I have a sticker!

Bad news! On the way home, something in my front end started squeaking, there was a soft pop going around a curve, then my steering wheel started oscillating violently, so I limped home. There was a lovely popping and grinding as I took a right onto one road and again on to another, and when I got home, my right tire has massive cracks in the sidewall - though it still holds air. 

I have no idea what happened. It was a little ponderous around the road before that, especially around the corners. 

Any ideas without me jacking it up yet?

Thanks

Vin
