I have a 2008 5.4L 4x4 F150 with 37,000 miles on it. I've had this issue with it, every once and a while when I slow down say I'm stopped at a traffic light or I'm driving through a parking lot at a low speed a loud clunking noise starts to come from the front left side and the truck starts shaking. The last time it happened I put it in reverse and it kept doing it, then put it in park and back in drive and it went away. Any help would be nice. Thanks
