Exactly!
Yeah, with weight on the adjusters the socket and LCA shouldn’t move independently as a whole assembly. But, the slop around that socket is space for the LCA to flex into or around on. The less space there is, the less room there is for twist/flex/deformation.
That’s not something you’ll notice driving around on bias ply’s, which is why the factory wasn’t too concerned about it. But slap some big wide modern radials with a 200 treadwear compound and 300 in/lb torsion bars and you’ll find all kinds of things get flexy.
