Actually I don't know that. I've been around far too many cases of it where the cause and effect were too tenuous to readily define.
I know what the root cause is but from there the causation and exhibited symptoms are too varied. I also strongly believe there is a correlation between damping from the shocks and instances of DW that hasn't been explored nearly enough.
I say we know nothing because what works on one rig doesn't work on another even though both exhibit the same symptoms. It doesn't matter how acutely you try and dig into the nuance of the equipment either because that information is typically filtered by the mechanical aptitude of the owner.
When faced with trying to distill information down into a hypothetical, I run at it from the other direction and I've done that many times to prove or disprove DW theories.
It's touted a bunch that toe settings affect DW. I've taken several rigs and set the toe on them to many angles and attempted to induce DW. If you can induce something and then make it go away, it is very easy at that point to make statements of certainty. Until then, it's all speculation.
I'm good with most of this. "too tenuous to readily define"? I didn't say readily....you've got wheels, tie-rod, draglink, trackbar and control arms, stabilizer, etc....
it's a finite system. I know one guy that just said **** it, replaced EVERYTHING in the finite system, D/W solved.
That's fine if that's how you run your science, from the theory back to hypothesis, maybe things have changed since I learned empirical process.
To your last point, my experience: after hanving replaced almost everything, including things that weren't broken...removed front lift, no D/W, put front lift back on, yes D/W, removed front lift, no D/W. New HD control arms, no D/W since.
