It replaces the rubber or polyurethane pivot bushing at the spring eye, which can deteriorate over time and cause loose steering, uneven tire wear, or suspension noise. The bushing absorbs driveline vibrations and allows controlled movement of the leaf spring, improving ride quality. It is typically replaced in pairs when the original material shows cracking or excessive play.
