Control arms

[gwinder]

The stealer told me some time ago the control was loose. Car was driving fine so I thought it was just him trying to make a few bucks. Anyway, he also told me the front brakes needed replacing....10,000 miles later he was right. Just finishing up that job...have to replace one of the calipers. Anyway, one thing I noticed before doing the brakes was a vibration in the steering which I attributed to the brakes but now I'm thinking maybe the control arm does in fact need replacing becuase in addition to the shimmering, I could feel a clunck as the wheel rotated. How does one know if the control arm needs replacing?

Thanks,

Gary
