Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
I would drive it in the air with a stethoscope and listen for the noise, this is probably a bearing noise. Without driving this is hard to diagnose.
Could be a carrier or pinion bearing in the rear end.
