pull with left arm or urn into right side ?

[snake]

Hi,
I have this feeling in my golf swing that I pull with my left arm as I go through the ball but I think this makes me come out of my posture, cast a little and get stuck at impact.
I tried not "pulling" so hard and turning into the ball with af eeling of my "right side pushing" and it FEELS BETTER but results are not convincing yet.
Am I on the right track ?
