Actually, I came across a video where the guy had a suspension knocking and it turned out to be a bad mount. I checked the exhaust and pretty much everything in the general vicinity of the front suspension, no obvious impact areas. Pulled the skid plate off and checked up there too. Haven't had an opportunity to dig too deep into the mounts, hopefully tonight.
Brought the truck to Firestone twice this week for them to look it over. They confirmed UCA, tie rod ends, hubs, and CVs are in good shape and not cause of issue. They can hear the sound but say its not related to the usually suspects.
I cannot replicate the sound by bouncing the truck, I have to drive and hit small sharp bumps to hear it. Also, have to drive less than 20 mph so I am wondering if its the strut. I put in a call to Dave Cortez at Eibach. I saw a brief post on a Colorado forum about a front end knock which sounds similar to mine.
I joke with my wife that fic for this issue is trading in the truck because I am beyond frustrated trying to find this noise. Its so loud and obvious, I can't believe its taking me this long to find the source.
