Tubular UCA install questions

Ok- did the trimming and have the first one so it will move throughout full travel from top until it hits the rubber stop at the bottom.

How easily should it pivot? Like should gravity lower it to the bottom, or is it ok if I have to push it up/down with moderate force?

What UCA bushings are in those tubular uppers?

It looks like they’re poly bushings. If that’s the case, they should be well lubricated and there should not be a lot of resistance to moving the UCA up and down.

If they’re rubber bushings, then you have to flex the rubber to get the UCA to move. But those aftermarket UCA’s don’t appear to have stock bushings.
