Installation Notes

Press-in installation is required for this ball joint. Verify the suspension configuration, part orientation, and fitment before installation. Because this part is pre-greased and does not include a grease fitting, routine service greasing is not part of its design. Confirm the locking nut and other required service components for your application before beginning work.
