Wheel Bearing/Hub Assembly
WARNING: This page is about a different car, the 2017 Chevrolet Spark. However, it is still accessible from the selected car via links, so may be relevant.
A single hub and bearing assembly is bolted to both ends of the rear axle assembly. The hub and bearing assembly is a sealed unit that eliminates the need for wheel bearing adjustment or periodic maintenance.
Although the rear suspension components are lubricated for life and require no routine lubrication, they should be inspected periodically for damage and wear.
