2003 GMC Yukon Grinding in the front right

Took my truck to Munroe to have breaks looked at, they said I needed new rotors and pads. Price was out of this world so I told them I would do it myself. On the way home I noticed a slight grinding on the front right side. I thought maybe they didn't get the pads seated and might be grinding on rotor. I got everything this week and did a complete break job to include replacing the rotors front and back. Took it out for a test drive and noticed the grinding still there turning left. So I thought it was the Hub and Bearing assy, so I replaced the right front hub & bearing assy. Another test drive and still grinding. I have gone over the entire front end and nothing is touching or grinding that I can see What am I missing, what else other then a bad bearing that could cause the grinding?

Note: I have lifted and checked the tire for movement side to side and top to bottom, no movement. I also spun the tire and can not get the noise to repeat its self at anytime with the tire in the air and no loadon the front end.
