If your truck is rear wheel drive (which it almost certainly is), you probably have a badly worn U-joint (universal joint) in the drive shaft, which will eventually come apart leaving you stranded with a big towing bill. This will vibrate at any speed, and much worse as you acclerate, but might let up as you ease off the gas.
In any case, no matter what the cause, you should have it repaired by a technician before you have a more serious problem.
its a chev try changing fuel and air filters
Variety of possiblities. The first item I would check is the center support bearing. It is in about the middle of the truck and the drive shaft goes into it. The rubber begins to give out and the bearing is no longer supported well causing a vibration.
I had a similar problem once and it had something to do with my brakes, I'd get them checked if i were you

why is my 1991 Mazda truck surging at higher speeds
If the chirping noise speeds up as the truck speeds up, check the u-joints in the drive line.
Unbalanced front wheel.
There are numerous issues that can cause a lack of power during acceleration. Common causes include a clogged fuel filter, a clogged air filter, and dirty fuel injectors.
Bad mount on the steers, worn/loose/damaged steering components, axles out of alignment.
It is called the venturi effect. The air pressure between the car and the truck reduces due to the relative speeds

-- First of all, you calculate the magnitude and direction of vectors. An object or a truck are not vectors. Things like their weight, velocity, and acceleration are. -- There are different methods and formulas for calculating each different vector. For example: . . . The truck's weight is (the truck's mass) x (the acceleration of gravity) downward . . . The truck's acceleration is (the rate at which its speed changes) in the direction in which its speed changes.
