Thanks Slowcrash.

It seems that when I lifted the suspension without the shock there was no noise....but I didn't know if that mean it was 100% the shock or if it was just from being un-tensioned.

I will double check the isolator bushings tomorrow but they seemed decent earlier. I'm looking locally for an oem shock I can 'rent' and swap just to drive the car around the block.

Switch one shock from one side to another. Check if it's still make the noise . That can rule out the blown shock

F#@&'ing A, this is the gift that keeps on giving.

Removed both shocks, and so both sets of control arms are there floating. I found a reliable way of replicating the noise (so shocks are not part of it, surprisingly). Removed the sway bar end links and I couldn't reproduce the noise. Installed autozone end links and the noise still occurs. Sway bar bushings on order although the noise doesn't sound like that, but who knows.

The way I can replicate the noise with both shocks off:
-Take my pry bar and flex the entire assembly downwards until I hear a pop.
-Let the suspension return to normal.
-Sharply jolt hub up and down with my hands....the noise happens in both directions.
-After a while the noise will go away....to get it back I have to flex the assembly down again.

Ok, so I've got a reliable way to reproduce the noise....however I can't for the life of me pinpoint where it's coming from.

Here's a video: [media]https://www.youtube.com/watch?v=4F7AFFsf3Qc[/media]

It almost sounds like it's above the diff but that doesn't make much sense. I put a pry bar to all the bushings and didn't notice anything out of place.

Your lower balljoint boot looks torn.

Does it only happen when the car is in motion, or after you move it, after its been sitting for a while?

Always in motion it seems over small bumps. Clutch in or out doesn't matter. I can't seem to make it happen by standing in the trunk and jumping up and down.

I had a clunk that I just fixed tonight. Problem with the rotor on the hub, easy fix. Good luck with yours

I get a "ping" kind of noise from the rear when I start moving in the day - I think it is just how the car sits and something is settling as I get it moving.

Have you ckecked the suspension bolts with lynch pins that none are loose - it sounds like something is allowing just a bit of play. Have you ever swapped your inner CV cups?
