Seems like a quality part
The installation was fairly simple in terms of what to do, not much harder than changing brakes. All bolts came off easy enough with letting some penetrating spray work for 15-20 minutes and a breaker bar. It took a bit more hammering to get the hub off the spline than in the video. Part seems quality, and a slight vibration is now gone. It remains to be seen if the ABS light that used to come in in very cold weather continues or not, but I'm guessing it won't. If you are somewhat handy, expect to spend 2.5 to 3 hours.

1A Auto should include a 6 point socket instead of a 12 point.
