i just changed my front wheel bearing and my axle but when i drive the car and is pressing brake to slow down i hear a sound (squeaky noise), so i checked my brake pads and rotors, and they seems to be fine but still making the noise, idk whats wrong with it. can it be the ball joints that is making the noise? should i just go head and change the brake pads? will an alignment stop the noise? or is the noise coming from the new wheel bearing?

please help ia... the squeaky noise is very annoying
