For the past 4 weeks i have been getting a noticeable humming sound when driving from 60-75MPH. Only when you coast then feather the gas peddle to stay around that 60-75 mark.
I finally took it to a Chevy dealer near my new job. (no buick dealers around where i work)
To my surprise the mechanic heard the noise and confirmed the sound was coming from the rear diff. Speaking with the service writer they or the GM dealer tech-line didn't know how to fix it. Went to pick up the car and they tell me they are ordering a complete new rear diff assembly.
