Deceleration vibration.
I have a 2005, F250, and when decelerating from highway speeds, I get a severe vibration in the steering wheel between 70 down to 35 mph. If I keep light throttle pressure, the vibration goes away. Any ideas of a cause would be appreciated.

Deceleration causes a weight shift in a vehicle. Does the vibration get worse when you apply slight brake pressure? If so, that’s all the proof you need that there is something worn and/or loose in the front end. Get the front wheels off the ground and start checking components.

There are so many things that could cause this. Check every part on the the front end for wear. Gotta get the wheels off the ground and wiggle em to see if there’s any play. Check all of the steering components. Have someone turn your steering wheel slightly both directions while you are underneath with your hands on various components. Don’t rule out the u-joints

Lots of potential issues. Ball joints, wheel bearings, steering arms/rods ends and bushings. First thing to try, though, is a tire rotation. If it stops after that, then the tires that were on the front need to be road force balanced.

Decel vibes are usually U joints. You may need to disconnect the shafts and articulate the joint as a visual inspection won't always find a seised u joint cup.
For the hell of it inspect all 4 caliper bracket slider pins (8 pins).
Inspect chassis suspension and steering components.
Check pinion bearings on both axles for play. Should be undetectable movement by hand.
