No but I was pissed after spending 4 hours putting in bushings and it didn't fix it.. Could the spring isolators be bad?

check the shock bushings...not the shocks themselves but the bushings under the carpeting in the trunk and under the car

The iso as in spring isolator the rubber between the spring and where it seats. Should be something on top and bottom.

If I put the back seats down and drive down the road it's really loud in the truck.. I haven't tested those shocks yet just the main ones.. If its that loud in the truck it's got to be the springs huh?

I have the same sound, I havnt gotten around to searching for it though. It really sounds like shock bushings to me. The quadrashocks could be the culprit. Might try some wd40 on the bushings and let it soak in.

So really, if its higher, what else is up there? just the shock bushings that go through the body. Weirdness.

Yeah but when I unhooked the main shock from the axle it still squeaked so I'm guessing the springs are bad.. I'd hate to get lowering springs because I have a procharger kit on the car and it rides 5 inches from the ground so any lower It'd get damaged

Sounds like sway bar bushings. Spray them with white lithium grease and see if it helps. And don't use wd40 it dries the bushings out I think.

It's got to be the springs.. It's closer to the wheels and more towards the doors to be upper bushings or the shocks

I dunno, the springs really dont move around much, but when you squash the rear end down like in your video your pivoting those arms, and they connect right up behind the trunk, explains why its so loud. Easy check would be to unbolt the axle side pop the arm up out of the way and try making the sound again. Wont hurt it to disconnect it just for that, wouldnt drive it like that obviously. Times like this is when I wish I had one of those stethoscopes (Probably spelled wrong) you cold put it right on each part and hear the squeek.

here is a link to the bushings, Im probably gonna get a couple sets soon.

It's the rear upper control arms!!! Finally found the problem! I greased the crap out of both of them and the sound muted some but not enough, so I'm going to replace the whole thing
