Was it a genuine Ford bearing or pattern part? My NSF bearing lasted 90k miles from new and I had it replaced with pattern part. This only lasted for 20k miles and was replaced by another pattern part. This one was defective from new........ droning and howling as soon as I left the garage. Garage replaced it, obviously free of charge and used another bearing manufacturer. Ironically, the car has now done 148k miles and the other three wheel bearings are still original.
