2008 Mazda 3 sedan, 180k miles

I can repeat this sound ever time, but I have yet to pinpoint what it is. Within the last 20k miles I have replaced the tie rods on the front, both lower control arms, full strut towers and both CV axles. While going into my garage if I have my wheel turned all the way to the right and give it engine a good amount of gas I hear two or three pops come from the front. The best way to describe it would seem like two pieces of metal under high stress and popping, like a spring under a load. All the previous parts were replaced just to do it since I hit the 150k mark I did some massive maintenance all the way around. It is loud enough when I have my GF drive it into the garage I can hear it perfectly but I cannot pinpoint it since the car is in motion. If the wheel is not turned to the full extent I do not think I have ever heard it. I also do not hear it going down the road or with the wheel turned the opposite direction. The front struts are the Monroe Quick-Strut. Is there something you are supposed to do to these before mounting them? Are they garbage? I may be barking up the wrong tree thinking it is the strut but I also do not want to get stranded.

sounds like wheel bearing.

If it were continuous while turning I would think so. This is one or two loud pops and then it quits.

I installed a set of Monroe Quick Struts in my 06 when I had it. No issues with them, so unless something didn't get tightened down all the way, I don't think they would be the issue. Have you ruled out the shroud in the wheel well catching on the tires? I did have an issue with a popping sound at one point that was also happening when I would be turning, and that's what it turned out to be (ended up wearing a small hole in the lower edge of the shroud). It had somehow gotten pulled forward, and the retainer was pulled through it. I just removed the retainer, and put it back in place after pushing the shroud back into place.

Yeah I have ruled out anything scrubbing the tire or the rim.

Finding noises is no fun...

I've had issues with strut tower bearings before.. but could possibly be the cv shaft?? If you can replicate the noise while driving slowly/safely, you may be able to get right up next to it. Try to figure out if it's coming from around the top of the strut tower or the bottom?

My first thought was the strut, which was replaced a few years ago. I have now ruled that out. Yeah even when you get close to it, the noise radiates enough to not be able to pin it down. Using a gopro it seems to be the loudest next to the wheel itself.

Wheel bearings make a growling/grinding sound when the vehicle is speeding up or slowing down.

Steering Wheel rack bushings?......Springs not "seated" properly?...Front Endlink hitting Strut??

Good idea!^ if you can get the endlinks off without mangling the hex insert hole or nut, go ahead and take them off and see if the noise persists.

I assume you've already checked the ball joints?
