Strange high-pitched metal hitting noise from rear..
Just letting you guys know that I've been doing plenty of research through this forum but haven't find any similiar issule..
I noticed this noise coming from rear couple month ago.. It didn't really bothered me but wondering where it is coming from..
It makes high-pitched metal hitting noise like once or twice only when you floor the car or down-shift to 2nd or 1st gear...
It sound like 2 metal is hitting agaist each other..
Anyone had similar issue?? It doesn't go any faster or slower with speed..
It only happenes when I floor then like once or twice... tick-tick or tick.. like this..
oh yeah.. I switched to OEM wheel to test but there's nothing to do with wheel.. because it still makes noise..
Please help.. I will try to post video clip if that helps~

This may be a stretch but, have you looked at the drive-shaft heat shield? Mine was falling and making strange noises like that until the tech got up in there and cut out the offending piece.
Buying a new one is stupid expensive, so just cut what you've got.

Hmm, it's a little hard to tell on the vid but, I don't remember mine sounding like that. The sound at 9 secs. is harder to detect but, the 17 sec sound seemed like you had dropped a coin on a concrete floor.
This sounds like a job for a professional.
Keep us posted.

It's not from the wheel, and not brake.. because they literally disassembly brake... where could it be???
Funny thing is.. It doesn't make noise as long as i easy on pedal...
and It doesn't happened all the time....
