Hi, I have a 2002 F150 SuperCab, 5.4, 4X4. I recently replaced the hub assemblies on both front wheels. Now, it feels like my brake on the front passenger side is locking up, and when I looked at it, I saw fresh grinding on the inside of the rim, so Im certain its not the brakes.

It just started today, while on my way to work, about 20 miles one way. Ill be driving it home, albeit very carefully, and taking a more indepth look tomorrow. Any idea of what this could be, or parts to check would be greatly appreciated.
