You would think that it would make noise when turning right but bearings can do some wierd things. I had a ford van that sounded like the left bearing was going bad so I changed it. Turned out to be the right, ruined the hub and everything when it went. Change the left bearing and check the ball joints while you are there. The play you mentioned, is it up and down or front to back? If it is up and down check the ball joints, if it moves front to back check the tie rod ends both external and internal. Since you indicated that the noise gets louder the faster you travel I would suspect that the bearing has gone south. Let me know what you find. Good Luck!
