Noise from Coilovers

ok so i just went out and confirmed that it is not any of my interior styrofoam bits. i took out a bunch of the stuff, and then stood in the trunk and kind of bounced a bit and was able to get the sound to happen. its def only from the right shock. the installer says that the preload is already maxed out, so its definietly not b/c it is not enough preload. they also confirmed that that rubber isolator thing that goes under the spring is most certainly there. also they said they never touched my sways and that those wouldn't have just randomly come loose. UGH
BC said that if it was a bad shock, it would sound like a loud hammering sound, and that if i want to rule out everything else i should switch the shocks from one side to the other to see if the sound moves from the right rear, to the left rear.
