If you lift the whole front end and put jackstands under the subframe, take both of the front wheels off and there should be almost no tension at all. After that it is just ten-fifteen minutes per link. However, as far as I remember/told, there are 3 desing changes to the links. Each have a different way of loosening style. you either use a 19 mm wrench to hold the ball joint and 21mm to open the nut, or 20-25 torx to hold the ball joint and 21 mm to open/close the lock. good luck.
