Rear suspension Squeaking (sounds like an old metal spring mattress)

[reb0957]

For about 2 weeks now, I have this god awful squeaking when the suspension flexes. Usually, I have the radio so loud I don't hear it. Thanks to my wife and my neigbbor, I was informed my truck sounds like a jalopy!
I found a thick silicone based lubricant and sprayed where the leaf springs attach in the front and rear. No fix!
Then I took that spray and hit every suspension point front and rear, including the torsion bars! No fix!
I sprayed it again at all of those places and body mounts! NO fix!
I am completely dumb founded! Any place that could cause that I could be missing?
I don't see the shocks being bad because they are Bilstein 5100s!

Yes. A few of us have had the spring packs replaced, me included.

Try your spray BETWEEN your leafs. If'n you don't want to goober up the springs, hose them down with a garden hose and rock your truck by hand and see if the squeak is gone.

Rear suspension noise

Anyone notice noise in the rear end? I hear it when backing out of my driveway onto my highly crowned street or if I stand on rear bumper and gently rock the truck sounds almost like a click or pop and then some squeaking

Yeah! Mine were replaced under warranty for the same issue and has been a bliss since.
