Booming sound from rear end over bumps
I noticed this noise after I installed the Downey Coils and Bilstein shocks in the rear. (had Revtek prior to this setup - and no noise) It is a booming type sound - as if the tire were dropping to full droop with a boom - yet It happend over small bumps too - So I'm fairly confident it'd not the shock reaching it's full extension, but maybe. Just tonight I drove over one of those little parking lot cement curb things (with just the passenger side tires) and as my right rear tire crested and started to decend I heard it --"boom" and then followed by the "boom" of the tire actually hitting the ground. So I know it's not just the tire noise - there are 2 booms. One as the tire decends and one when it contacts the ground.
Any ideas?

could it be a bottoming out sound? like maybe the bumpstops hitting or something like that? could it possibly be your driveshaft hitting your gas tank?
im not quite sure as to what is happening
maybe someone else has experienced something like this

Are you positive the coils are seated correctly? Your best bet may be to have someone stand outside the rig to see if they could better pinpoint where the sound is coming from. I can't see how going over something as small as a parking curb could cause the driveshaft to hit the gas tank, or to fully extend your shock.

That's probably not your problem, but it seems like it's difficult to tell the direction of noises coming from the back end. I think they bounce around the cargo area and make it hard to pinpoint.
