Since I'm replacing my dampers and springs, I was inspecting my other suspension pieces in case I needed to replace anything else. I noticed that the ball joint on the front lower control arm had been damaged. The funny thing is this was replaced back in March. I've been experiencing vibrations/thumping noises when I brake during highway speeds. Is this the culprit?

(I apologize for the poor photos)

Guess it's an excuse to upgrade to m3 bits

The possibility of a damaged control arm ball joint causing vibrations/thumping noises while braking during highway speeds?? Unpossible!!
