Hi folks,
2019 GMC Sierra 1500 with approx 127,000 kms (79,000 miles) and I'm getting a loud hum from the rear end.
My mechanic says its coming from rear driver side and is related to drive axle, not wheel bearing. Says to take it to dealer to see what they can do, as it should never have an issue with that low mileage.
Anyone heard of this issue, TSBs or recalls?
Thanks!
