Does your front tires have the same air pressure???
With one a little low, it'll pull, and vibrate. Check the simple stuff. The popping when turning one direction? That could be the steering stops rubbing the A-arm. I'll bet $$$ that your plastic caps are missing. Toss some thick grease on 'em and see if that goes away.
