It might be the strut, but I think a more probable issue may be you CV Halfshaft. When the joint in the shaft breaks it often results in a loud clunking noise when driving. If you get under the car you should be easliy able to determine if the strut is the problem, but the CV Halfshaft is a little trickier. Once you get to the shaft if it is broken you should notice a lot of play in the joint. It will move side to side and up and down much more than normal if it is indeed broken. Hope this helps and good luck.
