Possible front differential problems.

[Tonystewart]

I have a 2000 Tahoe 4x4. 180,000 miles. There is a slight hum in the front that is constant. When coasting or braking, especially in curves, it sounds like a hive of angry bees up front. When it makes that sound giving the gas shuts it up. The angry bee sound is not constant. The front diff has fresh fluid in it.

I just replaced both wheel bearings, both cv axle shafts, the master cylinder, all brake pads are new. It does it in 4 wheel drive or 2.
