WOW! What a read, for all first-time raptor owners who have a Gen3. I am having the same problem with my Gen 1. Seems to be an ongoing issue with Gen 2 as well. Clunk is felt in the floorboard at my feet/pedals anywhere between 5-25mph while going over smaller bumps. Feels as if a bolt is loose or my lower ball joints are completely shot. All have been replaced with HD Moog parts and clunk is still there. According to what I'm reading its been a re-accruing thing year after year with the raptor model . I'm still in search of a fix for "The CLUNK"
Best of luck to fixing it. Ill be following thread for an indefinite answer/fix. Thanks guys
