Scraping sound during acceleration
2003 4x4 5.4l automatic.
In December of 2014 I had the left front wheel bearing replaced. Recently, the same sound came back and seem to be from the front right. I changed out the hub and bearing assembly myself this time on the right side. Turned out to be a pretty easy task with a little heat. The swap took less than 2 hours and went smooth.
The truck sounded good and off I went for about two weeks. Now I'm hearing a similar sound. I hear it most when starting from a dead stop up until about 20 mph. Then it is either hard to hear because of road noise or it quiets down entirely.
Slowing down I do not hear it.
This evening I jacked up the rear and put it on jack stands. I first checked the fluid in the rear differential. It came pouring out after I removed the plug and seemed to be in good shape.
I started up the truck, put it in drive and let off the brake. I could hear the sound but it was not as distinctive or easy to hear. That could be because of the environment. My garage door was open, I live with my back yard on a busy street and there was a lot of traffic on the road.
I'm looking for suggestions on what to check next. I can certainly pull the truck in the garage on a diagonal so that I can close the door (venting the exhaust). Would you check other fluid levels? Transfer case, trans fluid, etc. or should I jack up the front and test the new wheel bearing?
The sound does not change when wiggling the steering back and forth.

And the answer is............
I took the right front wheel off last night and removed the brake caliper. In the groove between the two pads of the inner brake pad was a rock slightly larger than the thickness of the pad. Removed the rock, reassembled, test drove, and the noise is gone.
Thanks for all of the help.
Problem solved.
