Front End Knock / Cant isolate source

[Herr Leber]

I get a knocking from the front left of the car but cant pinpoint it. It happens when the wheel is just slightly tuning left, also when under braking, and of course on big pot holes(straight on or otherwise)

I thought it was the wheel bearing. I inspected, cleaned and repacked and tighened up. Still had noise.

Car has new ball joints last year. Sway bar secure. A arm bushings okay. Idle arm bushing set replaced last year but has a little play this year. Strut tops look replaced. Tie rod / center link looks okay.

Steering box could be culprit.

Any thoughts folks?? The left hand thing is buggin me.
