Re: Deceleration Hum
I would jack it up and check the bearings. See if there is any play in the wheels and rotate them by hand when elivated.
I also have a humming noise when coasting in 2wd. I jacked it up last weekend and found that the driver's side front did not spin as freely and made the mystery noise.
I ordered a wheel bearing/hub assembly and will be replacing it soon.
For the record I am at about 57,000 miles.
