Wheel hub and bearing fit perfectly and are identical to the original part. The only problem with this part is that it claims to fit my car as a direct replacement. If you look at the product picture on the seller's site, you can see that the sensor connector is round, has round pins and a flange on the side of the connector housing. The 2011 F150 XLT Quad 2wd 5.0 port cab is square/rectangular with two flat pins. However, this is easily circumvented by changing the wiring harnesses. The sensor is held in place by a single hex screw and is simply plug and play. So don't tear your old strap when removing it. (can actually save you a step as you don't have to remove the wiring harness from the frame, you can simply detach it from the hub assembly and loosen the first retaining clip on the wiring harness to make room to remove the sensor from the hub). All in all a great product, the only thing to look out for when buying is the suspension.
