She says it's not vibrating when she's braking. I'll have to drive it and see for myself. Suppose I should've already done that rather than just taking her word for it. I have already been under the car to check everything out which is why I'm still stumped. The only thing I didn't do was to put a jack under the LCAs when I checked the ball joints. I read somewhere recently that it makes it easier to tell if a ball joint is bad.
