Hello.. just had the front right ball joint on my 2010 A4 Avant replaced. It was very noisy at 60,000 miles. I know full well that the wheel has been hammered a few times. Now the car runs down the road as if on a ribbon of silk, but, it seems that as I come to a stop on uneven pavement the car pulls one way or another.

Question: Do people change both front ball joints at once? And also, is perhaps a alignment required? Or, worse case scenario has my local garage not up to the task? BTW the ball joint was not an Audi original replacement but a after market one.

Any thoughts much appreciated.

Thanks
