2003 Tribute part name help
 

Hi!

I'm happy Mazda Tribute (year 2003, engine 3.0) owner from Europe. Everything was perfect until something went bad to my suspension. So I've been asked by my mechanic to buy some parts. So I've found all necessary parts to repair it, except one. Now simply I'm facing problems with finding it on internet sale. Since this car is to some extent similar to Ford Escape maybe someone knows how to reach this part.

This part is selected with red arrow. What is the name of this part? Is it possible to buy such part?
Do I have to buy the whole part pointed by blue arrow? What's the name of this part? Where can i buy it? Any hints appreciated.

My suspect that part one is 'control arm bushings' and the part two is 'wheel knuckle'. But where to buy such parts?

Best regards
Piotr

I agree with the "control arm bushing" guess. Isn't part 2 the control arm itself?
