Strange howl at 45MPH

[1997_5.0]

Hey guys, on my 1997 Explorer, when driving at about 45-55 miles per hour, it makes a loud howling noise. I mean, with the radio on, you can hear it. But it seems to only make it when you have your foot on the gas, if you take your foot off the gas the noise stops. Any ideas?

Thanks,
Ryan

Huh? No, If the radio is off it will still make the noise, and it sounds like the rearend is going out, but if that was the case it would make the noise all the time. It will only make it when you accelerate, or have your foot on the gas.

Anyone?

it is likely the crown and pinion not being aligned properly.
pop the cover and put marker paint on the crown gear to see how the teeth are messing.

ya

it may be the axle but the 8.8 rear end is a really good rear end. It can be many things I am not very familier with 2wd. (WISH I HAD IT HAHA)
