Vibration while driving down the road

Could be anything. Nobody can tell you what the problem is from behind a keyboard. You'll get a bunch of guesses. Take the truck to a good spring shop. There are endless threads here about this. Probably one posted every week.

 

Every truck Ive driven where the steering wheel shook like that it was kingpins needed replaced...

 

I had a steering output shaft break, the one exotong the steering gear box, shop kept saying nothing wromg, till one night whrn ot made itself evident as to where the vibration came from. Cost them the tractor and trailers when the tractor rolled over. 3 weeks of write ups for vibration from the front end between 45 and 60 mph

 

Don’t guess, bring it to a good shop and have them go through it.

 

Your truck? Company truck?
