Once jacked up and supported at the sub frame, the strut will be fully extended. Remove the wheel. Then remove the tie rod end for the steering. Remove the castle nut on the lower ball joint. Separate there. You will need to remove the lower strut mount, and disconnect where it attaches to the sub frame. You will need to get a alignment done after your done.
