I cannot figure out what this noise is...

When I give the car some gas, for example getting to speed on an on ramp or just hammering it to go fast in general, and I let off and drive normal, I can here this noise in the rear passenger side that sounds like someone is taking one of those old metal antennas and pulling it back and letting go. It does it mostly over bumps and pretty much only after I get on it some. I crawled under there and cannot find anything unbolted or loose. I'm curious if its a spring going bad maybe?

This is for a 2010 GT. It has LCAs with relo brackets and a new adj UCA and mount on it, if that matters. No clue what's making the noise and its always on the rear right side.

When was the last time the LCA bushings were greased? Do you feel any side to side movement when you hear this noise?

I installed the LCAs last year and haven't greased them since. No movement. Just the weird old school antenna noise.

Emergency brake cable flexing or shifting? Wheel bearings going bad? I have no idea what kind of noise you're trying to describe.

Do you possibility have your exhaust pipes replaced with an off-road pipe? If you do, check the tightness of your rear o2 sensors.

I don't know how else to describe it. It sounds like an old school metal car antenna when you pull it back really far and let it go...I've tried to record the noise, but the loudness of the car drowns it out.

I have Kooks LTs with a catted h-pipe. I'll check that though. It sounds like its coming from further back than that. I'm certainly going to check the O2s still. This noise is annoying..

Check your rear shocks and make sure they're snug. My "buzzing" went away when I changed springs.

Worn swaybar endlink bushings of been known to cause an audible clunk, especially over bumps. Definitely a different sound than you are describing, but worth a look while under there.
