I don't do this real often, but sometimes I just need to get on the gas while turning left so I can get into the small gap in traffic. Get a bit of wheel spin and I get a terrible grinding noise that sounds like it's coming from front right of car during wheel spin. I first noticed this on Friday July 9th. I checked for wheel bearing play and as far as I can tell there's none. I checked suspension stuff and am not seeing anything obviously wrong, no torn boots on anything. Steering and suspension still feels solid when driving. The other thing I noticed right about the same time is that the engine seems louder (but not significantly so), especially during a cold start. It could be placebo because I hear one sound and now I'm looking for others because I don't like abnormal noises coming from my vehicles. Haven't replaced anything that would make it louder. The trim in the interior plastic also vibrates more at first cold start and during driving which also started at the same time. I know correlation doesn't always equal causation and these don't really seem linked at all, but I wanted to put that in as something I have experienced. I'm not really worried about the trim vibrating, it's a nearly 6 year old economy car, so it's expected. I mention it because it wasn't doing it prior and suddenly I'm getting a louder noise from the engine and more trim vibration
I don't feel any vibrations or noise from the front right when driving normally. The grinding only happens on a hard left with acceleration. I tried it with sport mode as well and it has the same result. My first guess was wheel bearing or CV joint, but wheel bearing feels fine as I mentioned and I spun the wheel off the ground and didn't hear any noises from the CV joint. I've had bad wheel bearings in my other cars and know what they sound like which is a constant low whirring noise when the wheel is spinning that goes along with the speed of the wheel and I don't hear that in this case. I've never had a CV joint failing on any of my cars but from what I read it clicks constantly, and I don't hear any clicking. My other thought is an issue with the transmission, but not sure how to diagnose that. I did try a couple accelerations when turning right and couldn't make the noise, so it's only left turns on the right front corner of the car to the best of my hearing ability when inside the cabin. I checked for loose plastic near the wheel and didn't see any. The sound is more metallic from what I can hear, but I'm not 100% certain on that.
Recent work on the car: Passenger side motor mount (torqued down with a torque wrench, but I haven't checked and they could have backed out), coolant replacement, transmission fluid replacement with Ravenol MTF-2 75W-80, spark plugs. About a month after doing that work I drove the car on a 3000 mile road trip that was uneventful as far as car issues other than getting the engine temps a bit high driving up inclines in Utah and Colorado. As soon as I realized it both times I slowed down and turned on the heater to full blast to help cool it down. It's been a month since the trip. Engine oil was replaced right before and right after that trip. Haven't noticed any drips or leaks from anything.
I had read something of an issue that sounded similar that someone had and they said once their front brakes were replaced the issue was gone after having replaced the wheel bearing that didn't fix the issue. I still have life in my pads, but there's a good sized lip on the rotor from wear. Probably time to swap the brakes. I replaced them before somewhere around 3 years ago and ~45K miles and I now have 93K miles. I used the brakes a lot harder my first couple of years of ownership. I didn't realize how much they would wear and ran them down to nothing for my first set to the point that the lip of the rotor was rubbing on the metal back plate of the pad. It's not there yet, but I won't wait this time.
I suppose I could just do a brake replacement and test but I was just wondering what others may suggest. It only does this when accelerating and turning left from a stop when I get wheel spin. I've done hard left corning at speed and did some fun turns around some roundabouts without any grinding when driving it to test.
