86 Fiero SE, How much effort should it take to swing the spindle assembly across its arc with the tie rods disconnected? A few years ago I replaced the upper & lower ball joints and today while doing some suspension work I had to use both hands with considerable effort to swing them. I regreased everything and they're still tight. I have power steering so I never notice anything at the wheel inside. Yes, the tie rods were also disconnected. Other vehicles, I can swing the spindle with barley any effort when the tie rods are disconnected.
I have the Rodney Dickman adjustable upper ball joints. Both sides react the same, extremely tight and they're well greased.

Most balls for suspension will resist moving by hand to different levels depending just how made.
Because Many have "springs" or other compressed parts to keep them tight.
So Any BJ and rod end easy to move by hand are often worn out and if don't have play now, likely very soon.
Go to Moog etc that show how they work or cut views of internal parts.------------------

Ball joints typically have stiction that develops when they are unmoved for some time. It tends to be pretty tough to move them by hand while new. I have steering system design experience and new tie rod ball joints tend to stick if they've sat even overnight. It's just a characteristic of the part. It develops after a couple hours of not moving and peaks out around a few weeks of sitting unused. Not inherently an issue with lack of proper lubrication.

Thank for the info Theorge & MichiganReefer. There's no end to learning.
