Had a "clank clank clank" coming from the rear - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So I had a metallic clanking sound coming from the left rear of the car. Heard it at low speed rolling in a parking lot.
Went under the car and searched for anything that was loose - no luck.

I then started tapping on components under the car until I heard the same clank sound again.
The middle of the aluminum wheel was the only item that made the same sound.
I removed the wheel and rolled it down the driveway....."clank...clank, clank"
Any ideas?

My assumption is that the tire pressure sensor fell off inside the tire.
If that is the case, it is wierd, because the sensor is still functioning - according to the car.
Anyone else have this issue?

Maybe part of it did? That is strange definitely. I hate to say maybe perhaps you 'll have to pull the tire and inspect the rim?

this might be the exhaust baffle problem. I have the same problem on my car. when you get just above idle is when I hear it. some people have had decent luck with getting it fixed, other (like myself) have not.

I dont have a ZL1 but it sounds like the TMPS Sensor came loose and is just flopping around between the tire and rim. Like ZL1-V said, pull the tire and see whats going on.

As long as the sensor is still inside, it should still function, whether it's still attached or not I would guess. It's a wireless sender.

It can sure take a lot of abuse. It has been bouncing around in there for a couple weeks. This would be a warranty thing, right? It failed on it's own and it is a sensor.

I would think that it should be under warranty. Only way to find out for sure would be taking it to the dealer.

On the other hand, if it was something inside the wheel that was loose, I'd expect it to make the wheel very unbalanced at speed.

I had a retard at less schwabe actually tape them inside a set of lexani wheels on my 300C because he never tried to just put them on correctly. I they came loose and I would have some wierd intermiten issues.

they lasted quite a wile before they failed completely

Here's a thought! Take advantage of that new car warranty and let the dealership figure it out!
