Whining Noise When Accelerating

[docharmon]

Recently (about a week or so) when accelerating I get a whining noise. As soon as I let off the accelerator it stops. I also now notice that when I come to a stop it seems like something in the back end sounds like its still moving, but the vehicle isn't really moving.

The Explorer has 190,000 miles on it and has never had any major issues and still has the factor engine and transmission.

Any ideas?

Ours did that and I topped of the gear oil in both diffs and it went away. May not be the same for you but its a good CHEAP place to start
