I have a 94 chevy silv k1500 truck. i have a grinding noise coming from somewhere in the front end. when i go for about 10 min and the truck gets warmed up all the way it begins. when i come to a stop its find but when sitting at a stop while in gear for longer then 3 seconds the truck starts to have a grinding noise under the floor. cant really hear the noise but it can be felt through out the truck. i cant figure this one out. there is nothing moving when it is felt.

It could be a number of things man but to be safe you may wanna get it checked out, or lift it up and see if there's anything down there out of place. Is your check engine light on?

there is no check engine light on. the truck runs just fine nothing changes when this happens. when im fully stopped but in gear is when this occurs. so i dont know what would be spinning in order to make this happen. it countines untill im over about 15 miles per hour but sometimes at 30 i can feel slight vibrations in the floor. there is no hesitation in the truck and it doesnt stop the truck from rolling in reverse or forward just makes a vibration. it happens weather in in 1, 2, D, O/D, or R
