Hi.
Got a 2016 Mazda 6 2.2D 175 hp AWD Station wagon, and at around 90-95 km/h (56-59 mph) I get this really annoying resonance coming somewhere from the rear transmission or trans axle.
It appears with both my summer and winter tires mounted.
Anyone experienced this?
What can be the cause, and more important: What can be done?

Cheers

 

Anyone?

 

I assume you mean the noise is from the rear differential?

Have you had the wheel bearings inspected? Has the vehicle been run at speed on a hoist and the driveline listened to with a stethoscope? Has the diff oil been changed?

 

Definitely some sort of vibration noise, at rather low frequency, but not something *I can link to the wheels.
Bought the car three weeks ago, and the noise was there. Wanted to see if it was the wheels and waited to raise the issue until I had my winter wheels mounted.
As the noise were still there at the exact same speed, I went to the dealer to have them take a look. They claim that my left rear wheel is crooked, which I find quite unlikely, because then my summer wheels would have the same issue.
I don´t think the dealer checked anything else. I do suspect it to be around the rear differential, as I also experience some sort of knocks, when gearbox shifts down at deceleration.
Could it be a worn joint somewhere?
Going to have my local tire dealer check my wheels once more tomorrow, to verify nothings wrong with them.

 

what mileage on the car

 

20.000 miles

 

so you have a warranty.try other dealer then.
