Hey Guys, I need some help here:

My 2000 accord rear sway bar end link started to make noise when turns even though it's just over 50k miles, tried to replace it myself over the weekend based on some previous posts, However, just can't seem to loose the bolts on either end of the end link eventhough the bolts are not rusted, also applied WD-40 the day before. Is there a better way to loose the bolts besides using a wrench? or you need some kind of power tool to do it? or I have to send it to a garage instead?

Many Thanks..
