My metal to metal "clunk" noise happens even on glass smooth pavement. I was sure it was the brakes until my local brake shop guy showed me the play in my lower control arm.
You can actually take the wheel (while on an alignment rack) and chuck it from side to side and reproduce the "clunk" sound I hear when I sometimes hit the brakes. It dosen't seem to matter if I'm going up a hill, down a hill, or on flat level ground.
It's just like what NORTHWESTTACOMA said: "I get it over bumps & stuff, but moreso when I apply the brakes. It's a really wierd clunk. Like someone tapped a wrench on the frame. I mostly notice it when backing up, apply the brakes & clunk. Then put it in drive, move a couple of feet, apply brakes & clunk."
I know there are probably dozens of things (like skid plates) that can make noises in the front end. I even found a TSB from Toyota that applies to 05 & 06 Tacomas that addresses an audible squeak or rattle in the front bumper extension (NVH NV003-06).
At least for me, I think I've found my demon...
