Review on ACDelco GM Original Equipment RW20-10 Rear Wheel Bearing: Precision Performance and Reliable Durability by Jack Collins

The ones I received must have been removed or "recycled". They are clearly not new or just tired of someone installing and returning. They are sealed in ACDelco bags. However, the ones I received should be dismantled or "recycled". they were dirty, old, burnt oils, not smudged fingerprints like you might see in an auto shop. But there were oily fingerprints on the bearing rollers. They showed more wear than the ones I replaced at 145,000 miles. Very disappointed and dissatisfied.
