I uploaded my own video of my car making this frustrating noise that I can't figure out. I've brought it to shops but no luck. The noise comes and goes. I caught it on a dry and "noisy" day and shot this video. Have any of you heard this before? Any input would be greatly appreciated. Drives me CRAZY!

Here's the video I shot of the noise:

I'm sure you've tried but I'll ask, if you try to zero in on the noise location, can you at least get a general idea of where it is? First thing that pops out of my mind is the hood prop "stick" but it's pretty amazing that you can make the noise by pushing on the wheel along with anything in the engine bay.

 

Thanks for the quick response- yeah I've tried isolating it with no success u fortunately. I've thought it was the comp rod bushings but they were inspected and are in good shape. (Also regreased all suspension parts while down there- maybe not good enough?) mostly happens when dry out- trying to see if anyone recognizes the noise. I'm stumped.

 

Ok here is what I would do in your situation. Jack the car up and put It on stands. Start applying pressure around the car like you did in the video. Grab each suspension arm while doing this to feel for the vibration causing the noise. This will lead you to the culprit of the noise. I'd recommend starting with the lower control arm and working around.

Here is where I believe the noise could be emanating from:
1. Damaged lower control arm bushing
2. Loose shock mount bolts (top or bottom mount)
3. LCA to lower ball joint nut
4. Maybe the shock itself (unlikely, but worth checking)
5. POSSIBLY a damaged or broken motor mount. (since you were able to replicate the noise by pushing on the engine.

Also, as far as the engine mount (which now that i think about it, is a serious contender), when you're under the car try moderately pushing up on the engine from the oil pan or something. If you are able to continuously replicate it, you may have found the issue. Good luck, and post back here with any results or questions!

 

What have you done to your car recently? and does this sound happen only in dry days

 

Haven't done anything- it can get really loud and sensitive to make the sound that is- when its dry. When it's wet out it usually won't squeak. But on a hot dry day it's like a nest of birds

 

Did you cross off all the possibles on my list? If not, prioritize checking your compression rod bushings and the engine mounts.
