Go to http://www.volvospeed.com/volvo_performance.php and then enter the Bay13 page and under the repair/maintanence page. You will find the instruction to replace the tailgate struts. I did it myself but you need extra help to hold the tailgate up at it's highest position to pop out the old struts. I asked my daughter to hold the tailgate for me. You can use a long piece of wood to hold the tailgate up.
