I adjust the split yoke on the cable so that there is even pressure on both sides of the cable. Because of the cable guard, one always ends up with quite a few more twists in it. After doing this, if there is still cam lean, then it is because the limb has twisted or the axel holes are not perfectly perpendicular to the limb. It' s easy to tell if the limb is twisted. Just take them off the bow and put them face to face and you' ll notice any abnormal bends. An improperly aligned axel hole is a bit more complex. You could fill the holes with epoxy and re-drill them, but unless you have the ability to precision drill a perfectly perpendicular hole, I' d try and get the manufacturer to replace them. From what I hear, axel holes can be a problem with some manufacturers.
