I had some vibration/noise from one of my front drums on my 71 Roadrunner. It was also grabbing and pulling hard right. I found the brake shoe lining contaminated with grease/oil. I had to replace the shoes. If your brake shoes were recently replaced I would just jack up each side and adjust to where the wheel will only make about a 1/2 turn when spun. Otherwise, pull the drum and inspect everthing.
