captainjman, i recently replaced my trunk struts (about 2 weeks) ago and i'll save you the trouble of reading the extensive posts on the subject. the above post is correct in that you basically have 2 options:
1) try to shave the ball (e.g., with a dremmel) to release it from the socket
2) buy a new ball stud
from the posts i read, it didnt seem to be worth the trouble of trying to shave down the ball (especially since i dont even own a drill). therefore, i opted for buying a new ball stud. the ball stud part is 90102-SL0-003 and only costs about $10 each. it litterally only took me 2 seconds to snap each ball stud into each trunk strut socket is u only need to lightly push them in to get them to snap into place into the socket. assuming that u buy new ball studs, the who trunk strut replacement should only take you 10-15 minutes or so as opposed to an prob an hour or more if you try to shave down the ball stud. and even if i did have a drill, i dont really like the idea of shaving down parts. seems like that would comprmise the functionality, reliability, durability of the part...but thats just my opinion.
trust me, i think its worth it to spend $20 (for 2 ball studs) for the peace of mind and to save u the time and effort.
