You can loosen the nut with a ball joint separator or are you saying that after you loosen it. Im trying to access it to loosen first.

 

you have the assembly off the car right?

You could use a wrench to loosen it, i think you have some space. if the ball joint starts spinning, you need insert a T30 or T40 I think to hold it in place while wrenching it. then use the separator to push it down.

attach pix pf what you have.

 

Got it installed on car, it was a T40 now I need to source a strut. I ordered one from a vendor and been waiting all day just to find out the order was never shipped.

 

Finally completed the change of the strut and lower control arm. Now I can go back to the electrical issues
