Steering binding on cold start up

[Rainman]

So lately my steering kind of binds, and I have to force it
Upon a cold start up. Usually it is quite mild, it it’s taking more force to overcome it, it has always worked fine after that. It’s also getting colder in the morning here.
No leaks. No squealing.
Any ideas? is it the pump or the box?
Something on its way out?
Any input appricated.

My guess is the seals in the box are getting hard and bypassing some fluid cold. Once they warm up a bit they expand and all is good.

valve in the box probably
