Good morning everyone. I had this replaced for $4600 at my dealership...because I was having the WHINE....now...at 100km - 120km....I have a hum...that fades in and out coming from the rear end of the car....if I remove my foot of the gas....it goes away....
Is this normal? anyone had their whole unit replaced? I emailed the dealership and I am going to be bringing my car in...
How long is the warranty for something like this performed by my dealership?

Thank you in advance.

 

Are you sure it is coming from the rear-end of the car and not from the transmission? If it is in the rear and the rear differential and drive shafts were replaced you may want to look at the wheel bearings or your tires.
