then i take a left turn it pops but not a right turn. then i start it sometimes does it and even when im getting out of my truck and shut the door it does it. it didnt start untill i got my alignment. i took it back to them and they drove it and it didnt pop. i thought thats what they would says so they would'nt have to fix it. the only thing they saw wrong was the driver side shock is bad. thats the same side as the poping, could this be whats making the noise?
