THANK YOU!! My fiance's '05 Aveo was GROWLING over 45mph and I figured it was a rear wheel bearing. Some internet research showed that it was an "assembly." Chevy dealership: $140.00++, Autozone: $35.00.

Repair was simple. Tire off, dust cap off, 1 1/4inch nut removed, drum assembly off. Reverse to finish. Torque axle nut to 145ft/lbs.

Searching this forum had all the answers i needed to be confident I was doing it right. I hardly broke a sweat in the Florida heat.
