Rear diff
I need to know what kind and size differential I have in my 99 e350 box truck? It has the 5.4l and the 4r100 trans. I was cruising about 65mph and I heard a sound like a tire blowing. All tires are fine but now I hear a rumbling noise over 50mph and its definitely coming from the rear end. Any help with this will be greatly appreciated

Its a DWR. it use to be a budget rental truck. I know for a fact that the the yoke going into the housing has a lot of play in it. I whines when I accelerate and goes away when I'm coasting, but now since that noise its rumbling.

I pulled the numbers off the tag but they mean nothing to me but here they are
4.10 VCX2S AA
606145-1
so I'm thinking its a dana 80 but not 100 percent sure.

Correct, you have a Dana-70.

They all do and their only purpose is to keep the nut tight.

Not all rear axles have crush sleeves. His Dana 70HD uses shims instead. The crush sleeve if for setting proper pinion bearing preload (the bearings require a certain amount of pressure applied to them) NOT for keeping the pinion nut tight. The locking pinion nut does that itself.
