Mystery front end rattle

Hey guys just trying to get some feedback here. The problem im having is going over any kind of bumps (speed bumps, washboard, offroad) im getting a mystery rattle sound coming from the front end. Ive checked common fixes like skid plate, heat sheild, play in my cv's, tie rods. Ive even had the toyota mechanic check it when he was changing a seal for me and he couldnt find anything. Its quite loud and annoying. Anyone have this problem? Thanks.

 

How do the motor mounts and radiator support look? Have you checked the torque on the suspension components?Can you tell what side of the truck it's coming from?

 

Update*
Turns out it was the slide pins for my caliper. Replaced them and bought a caliper spring and no more rattle!

 

Thanks for the update.
Most people never come back and tell us once they have it figured.

 

Yes I've noticed that. Took me a while ripping things apart but finally kicked my tire enough to locate the noise. I havnt seen a thread on this so not sure if its a common thing to have loose clanky slide pins...
