Uncontrollable shakes

I was cruising down the road at about 50mph yesterday in my 88 F350 Rack body and hit a major bump. The whole truck started shaking uncontrollable. It almost felt like being in a dingy when hit with serious waves. Almost a rolling shake. I slowed right down and it stopped around 25mph. I stopped and got out and went around and nothing seemed out of place. Tires were up, nothing loose. I got back in and started down the road and nothing rattled or shook and it didn't do it again, even hitting the same bump. The rear end has been rebuilt, before I got it so I can't alk to the ability of who did it. I haven't gotten under it today but my next thing is to check out the drive shaft and make sure the u-joints are ok. Any thoughts?

daved366,
Welcome to the IDI diesel forum.

Was the steering wheel shaking rather violently?

Probably death wobble, caused by worn steering parts and alignment.

Tie rod ends, king pins and wheel bearings.
Look for play in any of them.

A little in each adds up.

How are the tires wearing?
