Parts were installed today, found the finish was not the same on both hubs. the overall machining was good but not exact for both parts. We will see how they work once they are road tested. Note there was a 9 mm difference on one hub at the back plate as measured across the diameter that was not present on the other hub? Question as to why this was presesnt on one and not the other? It made for a very tight seating of the rotor. 10 15/2020 The hubs have failed! with 4827 miles of use the hubs must be replaced. What is the warranty? 1/15/21 no response to date from the seller about why the restock charge for a failed part? I followed up with Best Buy today.
