Question Help

Hope someone can help me out. I have a 83 Blazer fullsize 4X4 350 700R4. The other day I was driving home and my truck started to vibrate only when I let off the gas It's not bad while I am giving it gas. It feels like the tranny because while it's doing it if I put it in neutral it stops. A place to start looking or an answer would be greatly appreciated. Thanks folks

Sound's like the U-Joint's are going south.

Or

Have you lifted the truck? If so the pinion angle may be out of spec's and will cause a bad vibration.
