replace the struts that hold the tailgate open.
warning
the tail gate will need SUPPORTING while the struts are changed. better with 2 people due to the weight

Replace the 2 gas struts that hold the tailgate up....simple job, buy them from a motor factor who could well fit them for you if you smile nicely!
