Every time I turn right the wheels cracks, it was a mild noise at the beginning but now it's loud, like something breaks everytime I turn, and now it is even doing it when I'm just driving it slow and straight. what's wrong??

Fist turn the steering wheel fully in one direction and look at the outer axle CV boot see if it is split and depositing grease all around the inner wheel hub area, then turn the wheel in the opposite direction and look at the axle boot on the other side. If the axle boot splits grease gets out and no longer lubricates the CV joint causing it to wear. On tight turns initially you will hear a clicking sound that increases with speed and tightness of turn. It could be a problem with the differential as well but axle problem is more likely.
