If the top side of the shock is a bayonett style make sure you use penatrating oil on it before you loosen the nut then clean the threads with a wire brush, then use a small wrench to hold the shaft and work the nut off. Trust me if you dont and try to muscle the small nut off it may damage the threads and the nut will lock up half way off then you will have to cut it off, this is what happend on one side of my 03, other side went fine when i did the above
