Noise in the rear and the infamous GM Lean

[swest]

So I have recently swapped out my Pedders in the rear for the Belltech for smoother ride and had hoped the Pedders with the dead coil cut was part of my rear end noise. Well it isn't any better. The noise is like a clunk or rattle like spring Is shopping around in the perch, but it can be as its when the vehicle is settled, not going over bumps.

So I'd like some thoughts on the tweaks I'm considering. I want to get it "right" first before throwing more mods at it to get my perfect set up.

So here is what I'm working with.

2010 LS 2nd (because the price was amazing!). It's my daily and I drive with my family a lot on trips. I've run 24s, 22s and now my winter wheels which are 20s.

Suspension and mods that are impacting ride and handling.
Front - 2" spindles
Rear - 3/4 Belltech kit with the 5305? Springs, Street shocks, free travel mod and djm links.

My lean has gotten worse since building a custom box for a shallow mount kicker the fit "behind" the rear panel so I can keep my 3rd row.

Here is some of my considerations of next steps so let me hear any pros/cons etc...

1. control arm extenders - can't find them separately, hopefully Tony might have them without the whole rear hardware kit.

2. Upgrade the front struts to the belltechs with stock springs (good or bad idea)

3. Djm or belltech sway bars (once I find the noise)

1) disconnect rear shocks from lower axle perch and driver around block see if the shocks are doing it

2) what does the truck measure from ground to fenderlip all around?

3) I always have to do my strut mod lower on pass side usually drivers side front leans

4) in rear in order to get rid of the lean due to gas tank for local guys i cut the pass side endlink down on the djm links and reweld 1/2 inch shorter this works and have the same set up on my truck.

Do you have a set of the trailing arm extenders that you sell separate or only in the full rear kit?

I already have 2 sets of shock extenders that I don't need

the trailing arm relocators only come in complete kit.

what does your truck meaure from ground to fenderlip all around?
