I bought these wheel bearings to replace in my '96 I30. The metal is cheaply made and there is no dust cover (to keep dust/dirt off the bearing surfaces). I dented one of those bad guys and cracked the inner ring! Yes, I lubricated the surfaces with some wheel bearing grease. Then I had to buy one of the local O'Reillys. Luckily one of them was in stock! Next time I will go to [.] to buy Nissan Front Wheel Bearing OEM!
