I am about to attempt replacing the stock front upper ball joints with the camber-adjustable ball joints from SPC ( http://iapdirect.com/item.asp?invid=1136 , front only). Looking at the stock balljoint before starting, I can see how I would disconnect it from the spindle (hub side) using a pitman tool, but it is not obvious to me how to remove the other end from the upper A-arm. It's not obvious how it is even attached to the upper arm. Any advice? Thanks.
