My 90 used to do the exact same thing. I ripped both sides of the front end apart twice without a slight idea of what caused it. Repack wheel bearing reset pre load n such n she would still do it. I never did figure it out but it never got worse either. It won't be anything to do with bad shocks as this can go on for miles n miles.
I even replaced all 4 shocks to no avail, had the rear end apart with no problems in the rear wheel bearing/drums either. Rear drive shaft was good as well.

Jack it up and check your wheel bearings. Locking in the hubs might remove enough slack to eliminate the problem. Other than that, good luck.

Also check tierod ends and balljoints, lugnuts, systematically check the whole front end.

If the truck checks out, maybe it's you. Try cutting out caffeine.

Did you break down the tires to make sure there's not a bunch of water in them? I've heard of rare cases where condensation from a compressed air line builds up 'til you get a fair amount in a tire. Rides along okay until you hit a bump just right, then it bounces around and sets off a series of vibrations. Don’t know why locking the hubs would make a difference, but if everything else checks out,it might be worth checking. Keep us posted.
