It's not as hard as the thread on here i keep meaning to do a new thread. in fact if you want il upload tonight! But bacically you only need to lower the sub frame, then pull the steering colum, and with abit of a wiggle and twists it falls out. trust me im not the most hand of guys (currently looking and how to change brakes) and i did it on the drive way. mind over matter haha!
