CLANG sound Please help!! - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

pakunodafie · 12-09-2018, 02:30 PM

Clang sound like metal to metal banging each other, Sound coming under the car.
Totally random sometimes when I turn right or after speed bumps it's like I am draging a trashbin under my car, I already checked undercarriage no panels are loose. Heatshield is ok.

Please listen and see the video:

https://www.dropbox.com/s/6ntx911o8f...1_1_1.mp4?dl=0

Happened only twice.
1st - speed bump - Slow approach 5-10kmph after bump.
2nd - Turning right - 30kmph speed.

Please help which possible issue I am facing now?

Hello pakunodafie and welcome to the forum -

If it only happened twice, I wouldn't worry about it -

However, if you can't let it go, I'd suggest you check and make sure the wheels are on tight, then check the brakes. Maybe your brakes pads are worn down to the wear indicators or a caliper is lose or sticking.

Thanks buddy, Pads are fresh last month, Ill reseat them later and I am suspecting is heatshield might be loose a little bit, maybe hard turn and after speedbumps heatshield touch the drive shaft. and sometimes when cruising 100kmph redl ining the car there's some rock rumble under the car, might be a panel.

Some says its CV Axle. but need to check later.

Just an FYI, if our cars go up a slope at an angle and one of the wheels gets free it produces a funky clank sound

That sounds different, but hard to really tell because the low quality of the video. Can you point towards the section of the car? front/rear/left/right?

Sounds coming from rear middle of the car.

Does it also happen when you suddenly accelerate?

I'm thinking could be the 2 piece drive shaft / diff .. ?

Show dealer the video and point out the noise you're referring to?

Accelerating from 0 - 60 is smooth, when reached 100kmph and 7k rpm a weird noise coming under the car, sounds like small rocks chirping down the car.

But the clang sound happens randomly sometimes after speedbumps or after turning right.

pakunodafie · 12-10-2018, 11:38 PM

I sent it to the dealership, They cannot replicate the sound. So they did not fix anything.

I have 2 sounds issues.
1. Clang clang noise when turning or after speedbumps(totally random)

2. Random noise shows up like I am dragging a trashbin under my car.

humfrz · 12-11-2018, 12:00 AM

Did you check the CV joints, like you mentioned?

Is the rear axle nut tight?

Is the car stock? If not, what modifications are there?

Also, has there been any maintenance activities just before this started happening?

Well you can rule out CV Joint RWD cars do not have them. It's most likely a loose rattling panel. Also keep in mind this car makes sounds you have likely never heard due to the lack of sound deadening.

Is the exhaust rattling on something?
