This is a clip of my BRZ from over a year ago. Excuse the exhaust, but is this the noise you're referring to? |

I can faintly hear it at the 1:40 mark, but I'm not sure what that could be. Sorry!

From listening to your video, it sounds more like a crunching than a rattle. Does it feel different when it occurs as well? Sounds like it might be diff or gearbox... but I'm not sure.

Quite a bunch of spinning gears for a potential for brief rattling when spur/worm wheels when suddenly locked?

That's a torsen type a that does have a bit more gear lash than the type b used by the 86, but it would never be this loud, heck, a G80 locker isn't this loud

[ame]https://www.youtube.com/watch?v=5WdySzQtSSA[/ame] Ultimately same situation. Gears in standing motion until sudden input causing adjustment in torque transmittance which may be causing the rattle. At least for me, that's the direction the noise seems to be coming from.

If you're telling me rattle from the gear lash in the diff isn't getting lost in the super soft diff bushings, is making it's way up the driveshaft, through the transmission, through the sprung clutch hub and is showing up on the knock sensors clear as day, Fine, but do more than just throw the idea out there, test and investigate. At least I'm doing real tests to find it. |

2) my results would hold little value as my vehicle is not the same as your & equipment would be different - my results would be moot to you with various confounders. 3) you could easily slap on your sensors near/on the diff and check the peak sound wave oscillation. If its higher/highest near/on the diff, you're closer to the source. 4) dif bushings aren't as soft as you're putting it; if the sound is able to reach your ears, those very vibrations would be able to be picked up in the engine which is connected by solid metal pieces (vibrations travels better through metal than switching through air, metal, air, fabrics, and whatever materials it goes through to get to your ear)
