Hi did you have a rattle noise with the bilsteins coming from your back shelf where the speakers are & then disappeared once you placed stock shocks in
I just bought a 2007xr6 bf when I drive out the driveway bump over some bumps while driving etc I can hear a sound that sounds like a loose wire is rattling in the rear shelf where speakers are more so on the left side middle also it’s driving me crazy lol, I have checked the boot shaken the boot opened the cover from the boot to see under the speaker shelf and I can’t find anything loose anywhere, then we tested my friend slowly driving it over the end of the drive way bump an could hear a slight noise from behind left wheel, could this be 2 seperate issues, I would be grateful to anyone’s suggestions as to what it may be cos I’m puzzled
