Only bearings I ever use. And I change them every time I change tires. Might be overkill but if you have ever had a wheel bearing go out at speed you would understand

I don't know what is actually going on but I ordered this product and received only one bearing. I called and you sent me another bearing but in the book it shows 2 bearings in this kit. I did get the other bearing for nothing but the description for this item needs to be more clear.
