Odd front suspension problem

[saxart]

My 1970 LB has this odd front suspension characteristic. I'm hoping someone here can lend some insight. It is the original front suspension on this truck. I've jacked up the front end checking the tie rod ends and ball joints by trying to find movement at 3 & 9 O'clock, and again at 12 & 6 O'clock and don't see any initial problems

Here's the problem... When I first pull the truck out of the garage, the front wheels will be "squatted out". It looks like there is too much weight on the front of the truck. When looking at the truck from the front, the top of the tires look tilted inward, bottoms tilted outward.

After going for a short drive, the front suspension now looks just the opposite. The top of the front wheels will be tilted outward, almost looking like there isn't enough weight on the front end of the truck. What would cause this? It almost seems as if there is maybe some binding of the suspension travel going on?

Any thoughts you could lend would be greatly appreciated. Moderators: Please don't move this thread to the "suspension" section, as I would like to see if this is possibly something specific to our 67-72 trucks.
