Clunk question.

First off, I've posted quite a bit about axle wrap / weak springs. I'm prepared for a full on flaming as it may seem redundant. But I just want to know why my truck isn't clunking or has that shifting feeling when it's really cold ( 10 degrees or lower).

I can come to a panic brake from 65-0 which normally would make my truck clunk when I stop. But like I said when it's cold not a single clunk or any odd feeling. The rear end feels super stable and stiff.

What is the deal, is the bitterly cold weather putting tensile strength back into my springs? Or is the fluid in my old shocks colder not causing the rear end to squat and shift??? I DONT GET IT!!!!!

 

obviously no one else does either...
