Front differential noise
My 03 fx4 supercrew is making a grinding noise but I can only hear it when I'm coasting at low speeds. Me and my dad both thought it was the driver side axle bearing but after opening the differential and removing the axle itself, that doesn't seem to be the problem.
Our new theory is that it is either the carrier bearing or the wheel bearing. We are just not sure if the carrier bearing spins all times or just in 4wd. I would appreciate any assistance.

Could be the hub bearing assembly.
