06 4Runner - Humm noise from rear?

Hello everyone, I have Toyota 4Runner SR5 V6 with 90K 4WD. I started to noticed some low humming noise coming from rear of the car when engine is NOT under load (foot off gas pedal) and only (35-20MPH). For example when coming up on traffic light and you take your foot off the gas pedal or you breaking in order to stop. Around 35-20 MPH you hear this decelerating noise (only between 35-20 MPH). Originally I was thinking Rear Differential Fluid level.. I have checked it.. nope, but I replaced ALL diff oils, and transfer case oils, noise still there. Someone said, Tires... OK Went and got all New Michelin tires, noise still here. I need help!!!. Thank You very much for response. You guys are my last hope
