You'll also need to remove the tie rod end (assuming you've seen that already).
Here's how I do it, others may do it differently, end result should be the same.
-Leave the strut pinch bolt in (since you already have yours out, you can just slide it back in, no need to torque it)
-With the LCA pinch bolt removed, you should be able to pry down on the strut rod/LCA to get the ball joint removed from the spindle. You may need to use a small chisel to open up the slot in the spindle where the ball joint hole is, especially if the top of the ball joint stud is crusty. DO NOT use a pickle fork, or pry excessively on the LCA to release the ball joint stud from the spindle. Doing these things will risk ruining your ball joint.
-Once the ball joint is free of the spindle, remove the strut pinch bolt. You may have to use a mallet or hammer to free the spindle from the strut body, or you can use a chisel again to separate the slot and loosen the fit from the spindle to the strut.
-In extreme cases, you won't be able to pry the LCA out of the spindle. In this case, you can lower the subframe slightly to give you some added clearance.
