Corvette NVH
Hello everyone. I have an 02 Z06 that was rear ended by someone in an F-250. Took it to the body shop and they fixed the outside but they never fixed the metallic resonance coming from the body. The accident had dislodged the rear hard brake lines behind the diff loose from the 4 plastic retainers and have since been secured by metal instead. I will try to attach a video so people may hear the noise I am talking about.
Below I will list the things I have addressed in my quest to find the noise

Above is a link to the current issue. It only happens on left turns.
Myself and 3 others have ridden in the trunk of the vehicle and it seems to be coming from just in front of the wheel well which is why I removed the right fuel tank.
I have checked
exhaust for contact
lowered mufflers in case of contact with heat shield
Applied foam to parking brake cables that were touching the bottom of the tub.
Lowered right hand fuel tank and applied insulation around tank
Removed rear carpet

For giggles I wonder how many of you other poor souls know what this is and share my pain.

The first picture you show is a brake line mount and regarding your second video, I suggest you secure those brake lines. In regards to the noise, that is really tough without hearing it first hand however since your brake lines are not secured properly, I would remount those first and be sure that you leave a gap between the lines and the body tub (when routing near the tub). I recently replaced my transaxle mount and did not realize that I bent those brake lines above the transaxle just enough that during moderate/hard acceleration, that would rattle against the tub and make a horrible noise. Just something to consider/look at. Good Luck!

These will fit the holes on your cradle perfectly and secure your brake lines.
