Just FYI - it was wheel bearing that died. It was so bad, that when I tried to get it out, it split up.
After hammering for 2 days, the only way to get out the second part was to unmount the whole knuckle and walk to the nearest garage to use hydraulic press. They did that for 40$.
But when I was putting everything together, I've noticed that a dust boot on the upper control arm is cracked and grease is coming out. From what I read, that boot is not sold anywhere and I need to replace the whole arm as a unit. Is that true?
