I have a 2008 f-350 6.4l 4x4. Lately when i drive the truck hard and go from a stop light or stop sign there is a loud rubbing noise like something is stuck or held on, i can feel a vibration. Its definitely the front driver side. Its not the brakes because it feels like nothing is holding the truck back, just that the truck is pushing the parts free. It is only when the truck is run hard, maybe something expands when it gets hot?

Im no expert but I'm guessing its the hub. I know i have to replace the outer dust seal that broke a month ago, so i will be taking the hub off anyways.

The truck rarely sees mud or any off roading

What do you guys think? I don't think the hub is supposed to go this early

 

The truck has 100,000 miles warranty on the drivetrain, Let the FORD DEALERSHIP take a look at it, at least they will tell you what the problem is

 

Im going to try to bring it there soon. The dpf has got to go back on, and i have to ask them if my leveling kit voids the warranty which I'm guessing it does
