Popping sound from control arm

[wberry85]

Me and some friends headed to the mountains and hit the trails this weekend and every time my front would flex it would go BANG! It was a loud pop coming from right under my drivers seat. Only thing I can see down there is where the control arm meets the lift bracket thats connected to the frame. Everything looks fine so I cant figure out why its popping? I figured it might be the lock tite breaking up but it did it for several hours. Maybe it was just breaking itself since its really the first time I had it offroad? Ideas?

i dont offroad my truck and i do get a popping sound under my feet, i looked at the tsb's and found that it has something to do with the body mounts and a spacer needs to be installed
