Mysterious sound. I give up need help.

Ok so a while ago my car started to make this very low pitched cricket sound I guess coming from the rear of my car. If you can't hear well you may not hear it but I do hear it its very annoying. It is not present when the car is under say 30mph but after it is there. Doesn't seem to get any louder after 60mph. Just a consistent cricket type noise from the rear I have changed pads and rotors and that wasn't it.

I know when I'm driving and let off has its still there or when I drive and put in neutral while cruising and rev my car it's there so it's not engine or exhaust related. I need help I can't figure it out.

Have you checked to see if at your last service at the dealer they mistakenly added the Trunk Monkey Option to your car?

Seriously however I Had such a issue in my long past 2007 Pontiac G5, turns out it was an emissions canister making noise at times. It wont b that on your car but try to find out which side its coming from and see what parts could be the cause. High Speed read end gear noise is a howling sound, not cricket chirps so I don't think its that.

Do you have an axle back exhaust? If so check the metal hangers at the mufflers. I had two metal pieces that were rubbing together causing a cricket noise when I went over bumps.

Mysterious sound. I give up need help.

I have the same exact problem and there was a tread less than a week ago about it. The sound is coming from the trunk and there's no debating that. And it happens whenever I'm on the gas a good bit as well as going over small bumps. I drive with one of my backseats down and know for a fact it's coming from the back passenger side of the car somewhere in the trunk. Still clueless to what it is

Use lube, not wd40. Wd40 dries out after a few days.

Axle bearings tend to roar, not chirp and it would change with road speed. While you are under there, check shock and their mounts. Pay particular attention to the sway bar end links. They are notorious noise makers. Since the noise doesn't change with road speed indicates it isn't in the driveline.

is it speed sensitive (ie faster chirps @ faster speeds)?

if so check runout to axle flanges....I had a bent axle.

I used some rubber hose cut in half and zip tied it to the exhaust hangers. To rule out the exhaust hangers just grab one if the exhaust tips and shake up and down. If it is the hangers it will make the noise.

My problem was the metal that surrounds the rubber hanger was rubbing on the metal rod on the exhaust.

Holy ****, it sounds like the rear end is grinding itself to pieces. It really doesn't sound at all like your cricket sound description in your first post.
