The lift struts on my 1997 NSX no longer holds the trunk up. I already purchased the lift struts, and found it difficult to remove the old lift struts from the ball stud end. Has anyone replaced their lift struts, and can you share your secret to removing the lift struts from the ball stud end. Once the old lift struts are out, I figure a rubber mallet and a light tap should be enough to install the new lift strut back onto the ball stud. Thank you.
