Hey guys I have this 2010 toyota corolla LE that has been having this weird issue. I noticed when I get up to about 60-70 mph and take my foot off the gas it makes this odd knocking sound and can feel a thud under my foot. The weird thing is it never does this unless I go through the canyon (to get to Work) and then anytime after that while the car is still running it will make this sound once I get up to that speed. The video was once I got up the canyon and parked and noticed it for the first time. and at this time it started doing it while idling and turning my wheel a certain way I would notice the sound more but then the other way was hard to notice.
