I have a 2001 Dodge Ram 1500 4x4 pick up with 63,000 miles on it.

At about 60 miles per hour , if I let off the gas, there is this loud humming noise coming from the front right.

I had the tires rotated and checked the gear oil in the front differential and all is good but the noise is still there....

The humm lessens when speed drops below 40 miles an hour the dissapears

what could this be?…….I was told that if it was a hub assembly it would make the noise at all times and not just at certain speeds.

Might be worth checking the bearing on that side.
