my cars a A/T and as i drive down the road mostly in 2nt gear and i let off the gas i here a bang noise from the rear it only happen when i let off i thought it was a back fire but it its not that im a little lost to what it could be i put stechs on but that was like 2months ago

 

why do u say its not a backfire?

 

it just dont sound like one to me iv gotten used to the hks sound of the back fire it sounds more like something in my trunk hitting the sides but There's noting in there

 

k after looking at it for a week it happens when ever i turn to the left or i tap on the breaks its like a rotating banging when turning to the left

 

Better check in the trunk where the S Tech's mount. They bolt inside the trunk right?

 

yep all bolts are tight that was one of the 1st things i checked

 

I figured so, but had to ask.

Under braking would imply something with the rotors or calipers. Better look at both sides real close.

 

yea thats what i guessed i have a appt for the dealer to try and get this fixed

 

I have a similar issue. I got my car used with a Borla exhaust on it and when the popping started, I think it's just cause the air-fuel mixture is not combusting completely inside the engine and therefore results in combustion inside the exhaust (dunno if that's what a backfire is). I mean, we've all seen NASCARs with flames out the side-exit exhaust but I know my car can't do that.

I only say that cuz everything in my car is bolted tight as it can be. I have nothing like luggage or the like in my trunk, nothing in the back seat, and only a CD case in the center console where it can fit.

I shift good enough that I can tell it's not a jerking movement made by the car, it just feels, in my mind, to be a popping in the exhaust.

My Focus had a similar problem but only happened on bumps on the road, so totally different thing.

 

Check your suspension for broken end link.

 

Where should i look? Not too familiar with the suspension components.

 

well took it in to sears and they said its my drive shaft?

 

I'd take it to your Mazda dealer instead. They know RX-8s better than anyone else.

At the very least, get a second opinion from the Mazda dealer.

 

yea im having taken there tomorrow
