after starting my truck, and putting it into drive, there is














































































































































































































































































































































































































































































when I put my truck into gear and start moving . an overall vibration starts that pretty much vibrates the whole truck. It doesn't feel like a front end out-of-alignment vibration..and it continues when i put it in neutral, and continue moving...its almost like when you go over a road that has grooves cut into it...don't know if that makes sense

Check your u-joints. Might have one frozen up causing the bind. Does the vibration change at all with engine rpm?
