Glad that it was a simple fix. Given the sound in the video I would have suggested you check the blinker fluid level. That can cause a knocking sound. Also your shock absorber bearings may need to be rotated, any compentent florist can handle this. I woulod not suggest doing this at home. You may end up with a cracked block.
I was going to say check your underwear. Maybe you crapped your pants trying to get that puppy to keep up to speed with a beamer or or a VW Rabbit. Anyway glad to hear you figured it out and even got it fixed for a few bucks. Lucky...
