Cracking in the knees is very common and does necessarily indicate injury or cause pain. The cracking/crunching is called crepitus. It can affect different parts of the body, but it is common in the knee.
It usually happens when air bubbles develop in body tissues, but it can also happen when the tendons or ligaments snap over the bony structures in the knee; however, it can also be a result of patellofemoral pain syndrome (PFS), torn cartilage, or osteoarthritis (OA).
At the beginning of a squat or lunge, focus on hinging at the hips (rather than shifting your knee towards your toes. Try standing, toes up against a wall and starting your squat movement from there. You may find it challenging to get as deep in your squat, but it will ensure better squat form.
Also, the quadriceps muscle directly impact the knee joint, so stretch and foam roll the quads daily.
The cracking may not go away completely, but practicing proper form, consistent stretching and rolling of the quads, improving mobility of the hips and ankles, will drastically improve your body mechanics reducing risk pain and injury.
