2016 CX-5 AWD - The whine only is noticeable when at speed. Maybe 30mph and up. It is not the brakes. Rotors and pads just changed all the way around. While doing this, I rotated and tried to twist the wheel while it was up in the air to test the wheel bearings. All good with the possible exception of the left rear and it was not convincing. I thought I "might" be able to feel a very slight vibration in the spring while rotating the wheel. Still whines. At 60+mph I shift to neutral, engine winds down but whine remains constant with no change. I have read somewhere that a bad torque-converter will sometimes whine. Question I have is if it is the torque-converter, will it still whine when I shift into neutral or would it stop when in neutral at speed?

Thanks,
Greg

 

How many miles on the car? The torque converter moves with the engine. When you shift into N, and let off the throttle, the engine slows so the whine should slow. Have you checked the rear drive shaft for slop? The usual check won't work with it being FWD with a torque splitter. (Shifting drive to reverse and back and listen for a clunk.) Traveling sounds can be a stinker to track down.

If the whine changes with engine speed, it's in the engine or transmission. If it stays the same rolling down the road, it's in the suspension and axles. It could be a bearing, although those usually rumble or growl. I've even heard tired whine, not very often, but they can. If it changes on a windy day though, it could be a window or door seal.

 

Thanks for the reply. The car has 80,000 miles. No clunk when shifting. Nice and smooth. It does not wind down when in neutral, so I'm leaning towards wheel bearing.

Thanks

 

My tires used to roar bit until I rotated them then it went away. Now they roar all the time and as I slow, I get a rumble from the front end. With the roads I drive, I suspect bearing failure.

Mine don't whine. They know better. If they have a complaint I want to hear about it but NO whining!

 

"Whining Noise that gets louder with speed"

That reminds me of my wife when I take her for a ride on the back of my motorcycle.
