Revisiting The “death Wobble”

The front end and tires violently shake until I brake. And as I said, seems to be when turning, low speed and hit a spot of pavement that's uneven, kinda like a shopping buggy with a bad wheel that shimmys too and fro.
I did do it once going over a speed bump, it's like something comes out of alignment and gets bound up/out of place momentarily.

 

the play I mentioned and when I say "suspension" I meant "steering":


I see how it's assembled via:

 

Don't throw parts at it.
You have a simple balance, or alignment issue or like mentioned your not really in 2wd.

This is when you throw parts at it. (Or replace it all with a Saginaw conversion) this is the smaller diameter bellcrank bearing.

 

Try having someone else turn the steering wheel back and forth repeatedly while you look underneath for movement where it shouldn't be. Like in JW60's video. Seems like to have a shake at that low of a speed something must be very out of whack.

Do you have extended shackles? Any shims between the springs and axle?
