Winning when foot comes off accelerator??

Whenever I take my foot off accelerator I hear a faint winning noise and right my foot goes back the sound goes away. What is this noise? Wheel bearing or pinion seal or bearing? Or something else?

Pinion bearing.

Most probably backlash on the pinion. Under load it sets properly but when the engine is being driven by the wheels the pinion backs out a little bit and the gears mesh wrong.

I get this as well, but it's only when in gear and coasting(5sp). I figure it's just the coast side of side of the ring and pinion and the tranny gears working in the reverse direction. It sounds similar when in reverse.

You need to do the bearings, you have noise because the front bearing is going away, do them now before you cost yourself more.

Do all of them, you have to take the carrier out to get to the pin bearings, which is most likely the front bearing thats really bad, but do all of them when you do

Sounds like a pinion bearing or loose yoke. If the yoke is loose, you may be able to get away with replacing the crush sleeve and pinion seal, then re torquing the pinion nut.
If you need to replace the pinion bearings, then as stated above, probably wouldn't hurt to do the carrier bearings as well.
Don't "just replace" them. You need to get a picture and backlash reading prior to dis-assembly of the old gears.
Double check the picture and backlash after the new bearings are installed.
