2008 ford f-150 truck vibrates badly even worse on let off gas?

Most common causes of vibrations are wheels out of balance, defective or damaged tire, bad U-joint, failed motor mounts or faulty suspension parts. With the fact that it gets worse when you let off the gas I'd suspect the problem lies with the wheels or tires. F150s are very durable trucks… But we don't know the mileage on yours. That factor could eliminate several possibilities.
