Clicking in rear wheel area

When I drive slowly around my neighborhood I can hear a clicking in what sounds to be the driver's side rear wheel area. It sounds identical to when you have a rock or nail, etc in the tire treads, however the tires are all clear.
It seems to click once with every tire rotation and naturally gets faster as I accelerate.
Anyone ever experience this?

 

My front right center cap does this.

 

Well I initially thought it was the center cap plastic area around it since they creak, and click. However Im not 100% certain that is what it is

 

If i walk around my truck and try and move the center cap, the front right is loose whereas the remaining 3 are solid. Windows rolled down and driving at low speeds it makes a clack, clack sound that escalates as I drive faster. Was replaced under warranty but failed a second time.

 

Hmm interesting, I'll check if there is any freeplay in it tomorrow as opposed to the others

 

Did someone put a rock in your hubcap? Oh yeah, that was someone about 50 years ago…

 

Thank you for finding this! Mine has the exact same symptoms from the driver's rear and I never could find the cause. Sure enough, after reading your post I checked my center caps and all were tight EXCEPT the driver's rear which has some left/right play in it.

I can live with it for now and will look for a replacement and see if that helps.

 

Looks like all of my center caps are tight with now freeplay......Now onto the next troubleshooting step whatever that may be at this point
