Clicking when driving at idle speed

[InuHasa]

Been looking around here for a while and getting a answers on how to fix up my sport trac, so today i decided to join cause I have a problem that I am completely stumped on. Onto the problem....

When im driving at idle speed, or at low speeds, say, less than 20mph I have this clicking (like tin clicking?) sound that seems to be coming from my driver side wheel area (possibly under the truck?). It dose not click when I am in reverse only when driving forward. it does not matter if i am turning left or right at low speeds I still hear it. I do think the clicking noise speeds up as i accelerate (hard to tell from the wind and such).

I just replaced 3/4 wheel bearings, two being the front ones, so I do not think it is that. Checked the cv joints and they don't have any cracks in the boots, they also have the normal play in them. I also checked the drive shafts and they dont have anything wrong with them, no leaking and no play.

Any ideas?

Thanks.

oh its a (early) 07 sport trac 4x4

Check your brakes, when you hear the sounds will it go away if you lightly apply the brakes?

try lifting it off the ground if you can. move the wheel by hand and see if you get any clicking

I think it might be the caliper pistons....when I changed the bearing both pistons has some chunks off from it...sound dosent change when I apply the brakes. The clicking also seems to stop and turn into more of a rubbing sound at highway speeds.
Coming home from work today I also noticed that there little to no vibration going at highway speeds just like something rubbing improperly. The noise slowed as I hit the brakes, no vibrations resulted from it. then idleing down my neighborhood the clicks came back.

i've done that. spun it around as fast as i could with a ratched hooked up to one of the lugs. I didn't get any sound (clicks) coming from anywhere.
