It sounds like the flywheel but it's become a bit more unpleasant, I can't tell if that's where it's coming from or if there is something that's come loose underneath.

I had my car aligned a few days ago I guess they may have damanged something when they took it off the rack.

Any suggestions are appreciated.

 

rear axle bearing theres a thread on this

 

I already had the rear axle chirp fixed.

The noise I'm hearing is coming from the transmission area. When I had my oil changed I had valvoline listen for it underneath and they said they could hear it coming from there. I have an appt with Nissan on Monday.
