Installation Notes

Compatible With 1985-1986 BMW 735i front right lower suspension service. Verify press-in ball joint service requirements, mounting hole diameter, and thread specifications before installation. Because the ball joint is already installed, this assembly is suited to replacing the complete lower control arm unit rather than servicing individual wear parts. Part number 520-728 should be matched to the vehicle’s suspension position before ordering.
