Truck vibrates like your going over rumble strips. When you accelerate doing about 50, at a slow accerleration. Let up on gas peddle and vibration stops.

Hello,

Sounds like an issue with the drive shaft. There could be a few different reasons why.
The best course of action would be first to do a thorough inspection of the drive shaft.
Inspect the U-joints, the yoke. Also, the mounting point for the drive shaft.
It could be due to any one of those components.

This can also happen due to an imbalanced propeller shaft/drive shaft. Which will vibrate, especially under load.

I have attached diagrams for the drive shaft as well as how to check for imbalanced shaft below.

Please let me know if you have any questions.
Thank you.
