Source of Rattle under a 2016+ Mazda MX5 (ND) and How to Fix It.

Many ND owners mention a rattle when slowing or when their car is idle. This might be a source for that rattle. A damper at the back of the transmission.

Thanks for posting this. Was having a vibration that sounded like it was in the dash, but I couldn't isolate. When driving, I had a pinging, like there was a loose heat shield, but I couldn't find one. Mine was not nearly as bad as yours. I could feel it was loose by wiggling it by hand, but touching a mechanics stethoscope on it was enough pressure to prevent rattling. Removed it, and sounds have gone.

[@DaveSimkus]

Any issues with having it completely removed?

[@Guenounovitch]

That’s funny for me that was the broken gearbox lol. Cute car

With the thickness of the frame I'd put a thread in these holes and screwed directly into them. Not everyone has a tap though. Thanks for showing this.

I used J-B Weld and it worked great

[@mikeb9569]

If the engine guard or splash panel or whatever it is that has to be removed for an oil change isn't tightened enough, it will cause creaking noises.

You’ve just added 5 grams of weight to your car ;)

Now I'm wondering if mine is loose/rattling??? Don't really notice it.

[@GRINHELL]

Only the 2.0 has this counterweight, the 1.5 doesn't.

[@josemarinobernardez7511]

What is that part?

[@zimotheone7402]

[@kentbigdog1]

[@zimotheone7402]

@@kentbigdog1 thanks man , I'm have a strange noise from under the car and I'm checking

[@matthewkilzi8543]

I just freaked out too haha I just checked and didn’t even have it

[@ashesdrivered.9123]

Spray foam?

[@kentbigdog1]

It would have to be able to withstand the heat off the exhaust. But yeah, that might work.

[@RaDeuX]

What size bolts did you use?

[@kentbigdog1]

I couldn't tell you as I pulled them from my bolt bin that has hundreds of bolts in it.

[@RaDeuX]

I ended up using M5x12 bolts. Thanks for the video, the rattling noise was very irritating and embarrassing.

[@Crazybelizean95]

Was the rattling pretty loud? Mine is pretty bad but I’m going to check this tomorrow morning

[@businessmanph]

6800 to 7000 rpm

[@allimikej]

Two words . Duct tape

[@kentbigdog1]

Too much heat as the exhaust goes by there.

​@@kentbigdog1 big facts. the first thing id do is slap a piece of electrical tape on that and call it a day haha
