I have had the same issues ; my control arm has been replaced twice in the past 7 years and is due again. I maintain the same tires on the vehicle so I don't understand it. I guess it's a design flaw.

knocking on front left side, replaced front arm bushings
I was in a car shop to have my tire rods replaced, outer on one front side and inner end on the other side. Incidentally, the repair guys also found out that BUSHINGS are worn out as well and needs replacement. I have to only opt for the tire rods work and hold off on having the bushings replaced. It is not really of a safety issues I was advised. However, they said I might need to check on my tires for uneven wearing of the tread, and by that it means I need to rotate my tires diligently as necessary meantime I still haven't gotten new bushings in place.
