Hi, my name is***** humming noise from the rear will either be noisy tires or noisy rear wheel bearings or noisy differential bearings.

I'd start by checking the tires for feathering. If the tires are good I'd suspect the bearings. A technician can listen to each bearing on the lift with a mechanics stethoscope to locate the source of the noise.
