Okay so I've had my car back for 3 days after the rear end collision I was in and since day one of picking the car up there has been a grinding noise coming from what I presume to be hub they rebuilt and replaced it with. I lifted the car today and spun the wheel freely and it makes no noise at low speeds. I shook the top and bottom of the wheel to test the bearings on goths sides and there's no play, I pulled back the dust covers and still nothing. I even did the turning test while driving and still no change. What's your guys thoughts on this? The Ford dealer is claiming the bearing is bad but didn't even test it.
