Anyone experience a trembling in the drivetrain when they give it gas, seems when i let go of the gas it stopps but once i press the pedal again it shakes. On the highway around 60 it shakes a little more, anyone know whats wrong

 

I would almost bet that it is the drive shaft out of balance.

 

If it was the drive shaft, wouldnt it do it whether you are accelerating or not?

 

When my truck was just a little out of alignment it did the same thing. I took it to GMC and they realigned the toe and it still did it. I then took it to a specific alignment shop, they did a complete alignment, which got rid of the problem!

 

Try replacing the U-joints I had a similar and that fixed it

 

a friend of mine experienced pretty much the same thing in his dodge when the rearend broke on him. busted the stock posi unit and it would shake and pop and all kinds of wicked ****.
