Hi all,
First off, specs.
2013 BRZ, 95k (kilometers
), AT, the only modification are a K/N drop in air filter which has been in since 75k (kilometers) and
DBA T2 slotted rotors . Also never been tracked, nor driven hard. Serviced regularly, however the shop I used recenlty actually used 10w30 oil.. not sure if this could be an issue.
When off the throttle, at speeds in excess of say 50 kph (circa 30 mph) I hear this faint hum or metallic grinding, which doesn't sound great. Although performance isn't impacted.
This to say that I can 'feel' the sound I am describing through the steering wheel and both pedals when it occurs. Here's the kicker, it gets slightly worse as speed increases and especially more pronounced when I turn right. In addtion, the vibration and noise, sort of, well, pulse when I am turning right at speeds over say 60/70 kph.
I will be taking it back into to shop in a few days to get them to have a look I just thought I'd see what you all may think!
I don't feel like it's an issue with the engine however it may be another part of the drivetrain? I also got a wheel alignment about 10 months ago if that helps.
