Itll be the front end shackle pins and bushes,or a tyre getting some age and the belt starting to let go ......
If it was an unbalanced tyre/wheel itll shudder slowly and increase with speed

Check your tyres , they have manufacture dates on the sides,if their old that could be it
But the front shackles, bushes and pins id say are stooofed

Chect the locator pin for the leaf spring to the diff and the u bolts while you are there

[Ferret]

my leafs shocks and shackles are all rooted badly if this helps not sure leafs are dead front and rear my bum stops are touching diffs lol

Check the inside walls of your tyres one may have a huge bulge about to pop.This is a Major problem that needs addressing ASAP

X2 on bushes you may be running metal to metal

All of the above.

To check the king bearings, jack a tyre up.

King bearing / swivel bearngs - Grub hold of the tyre at 12 and 6 then push back wards / forwards is there any movement.

wheel bearings - grub the tyre at 3 and 9 push back wards and forwards any movement

Also check the welds on the chassis where the schakle eyes are

ROD,

FINLY was doing the same thing. I studied up on this, and became aware that many things can and will lead to the same problem. I have now done all wheel bearins and swivel hub bearings and have no "death wobble". Swivel hub bearings are what many refer to as "king pin". All other bushes etc if worn exagerate the problem
