Screw size for tension strut and guide joint?
 

Hi all. I am going to replace both tension strut for my 2001 X5 4.4i. Before doing that, can anyone tell me the screw size of number 9 and number 16 in below link so that I can prepare the tools? Thanks a lot!!!

Now I know that the nut of number 9 is 21 mm, so anyone know the size of screw of number 16?

16 is a torx if I remember correctly, but you will not need to remove that ball joint unless you plan to replace it. That ball joint is not part of the support arm.

Thanks!
