I did a side job wheel bearing on a avalanche once. He bought a cheapo Autozone bearing.
I put it all back together and test drove it. At 45 MPH it came apart.. Wheel took off across the street, almost took out a new BMW. Caliper, rotor, etc all connected to the wheel.. As I went sliding down the street and made it to the side of the road.
I will never use duraCrap again.
