My truck has a weird shutter when you begin to accelerate from a dead stop. The shutter also happens when stopping. It feels like the U joints are going out, but no noises. No sounds coming from anywhere, just the shutter feeling. Maybe the frame bushings are going out? I am totally at a loss. Everything that moves or articulates underneath is tight, with no visual signs of leaks. Any help would be greatly appreciated.

 

Could be bad U-Joint(s) in the drive shaft binding the driveline. Bunding U-Joints normally don't make any noise. U-Joints with crushed needle bearings will normally clunk.
