Hey guys I have a 07 g35 v36 sedan and I’ve been having this problem with my sedan where there’s this constant whining noise. It does get louder when I’m on the interstate and I’ve been told it could be my wheel bearings or motor mounts but I’ve checked out both of those and they seem fine. Definitely coming for the front of the car I can feel the whole shake a little especially when I’m going faster. Hoping someone can help me out thanks in advance.

 

Did you isolate that issue? I would first check the tires for cupping or internal damage by either free spinning them or take the wheels to a tire shop that has a 'good' balancing machine.
I have a 07 Sedan and i always hear the front wheel bearings on the highway even tho i've replaced both sides and still that humming noise is there. Granted, i do have all Nismo shocks and springs from a 370z and it's 1.5" lowered front nd back and I also have new brakes, straight wheels and good tires.
These V36s were not the best design as to being 'cabin quiet'. It's more of a 4 door 350z than an Infiniti..
