How to Change the Wheel Bearings on a 1998 Sunfire

The 1998 Pontiac Sunfire shared a platform with the Chevrolet Cavalier. The Sunfire was fitted with a 2.2-liter or optional 2.4-liter inline-four cylinder engine. The Sunfire used MacPherson struts to provide independent front suspension. The front wheel bearings on the Sunfire are part of a hub and bearing assembly and must be replaced as a unit. The procedure is the same for either side.
