High enough quality for a great replacement, much cheaper than the dealer. It's worth buying if you're replacing a wheel bearing rather than trying to take out the original bearing race that usually gets stuck there when you pull the bearing out of the knuckle. Save some time. A small disadvantage is the included axle nut, which cannot be screwed onto the axle. No big deal, I used the old axle nut anyway. So if the axle nut is bad, it might be better to get an OEM from Toyota.
