Roller ball bearings work well for smaller cars, but replacing a tapered bearing with a roller ball bearing increases wear and failure Fits: 2011-14 Ford Expedition 4 Wheel Drive Front Wheel Bearing & Hub Kit 2011-14 Ford F150 Truck 4 Wheel Drive with 6 Lug Wheels Front Wheel Bearing & Hub Kit 2011-14 Lincoln Navigator 4 Wheel Drive Front Wheel Bearing & Hub Kit
