I've noticed the sound for the last couple of years. It seems like it happens pretty often and regardless of if the truck has just been cranked or running for a while. I really started noticing it whenever I'm driving next to something like large buildings downtown, and the sound echoes back. It's not ridiculously loud, usually I notice it when I'm driving downtown with the windows down and a lot of times when I put the truck in reverse pulling out of a parking spot. It basically sounds like the "clank" of an aluminum Coke can, but obviously louder, from underneath the truck. Also, it isn't the brakes, I already looked at those threads and it doesn't happen when I press the brakes. It doesn't seem to really do anything else after it makes the clunk sound and overall the truck seems fine. The noise is just really annoying and I can't re-create the noise to look for it myself. I finally thought about posting it today for the first time, does anybody have any idea?
On a side note, I have the OME lift, 885 coils, nitro shocks all around, AAL, and the 1/4" spacer I think. Will upgrading UCA's make my front suspension ride a little smoother and not feel like it's "bottoming out" so bad?
