My engine glass gas struts are weak, made worse by the cold weather (hopefully on the way). I've got some SOS replacements, but I'm having trouble removing the OE struts. I planned on just removing the lower bracket and then upper ball, leaving the OE struts and upper and lower attachments all connected (since SOS comes with new hardware for each end). However, the upper OE ball joints are not coming out of the glass frame easily. I fear continuing to use an open 12 mm box wrench on them will round the shoulders. Can the top ball of the OE strut be popped off the ball joint so that I can get a 6-point socket on it instead of the box wrench?
