XRAY - Model racing cars

Hi everyone,

I have a question about my shock ball joints and my pivot balls on my T4 2015. I have read the manual very very closely and still I don't get it.

The situation how I have my shocks installed is:

Top part of the shock, shiny part pointed TOWARDS the pivot ball.

Bottom part of the shock, shiny part pointed AWAY from the pivot ball.

Now this; I try to move my ball joints freely over the pivot balls, but on the top part of the shock, the ball joint does not move freely. I mean by that, it some sort of "sits" at the base of the pivot ball. When I try to wiggle it, it has a restricted movement. But when I pull it out a little bit, the ball joint moves freely. It looks like it "clicks" into place when I don't pull the shock out.

(The worn tires are just there for other reasons...)

Is this normal what you see on the video?
If not, could anyone tell me what's wrong here?

Thanks in advance!

My shocks are exactly the same, when I built them.

Newness!! It will wear in

They should be freer than that though. Unless you want to try and polish them with a dremel tool or sand paper I recommend you to ask your LHS for replacements.

Thank you Alexander and others.

I have polished the balls already, no difference.

I contacted the distributor as well and they send me replacement parts. At first I thought they where better and the issue has been resolved, but after asking around at my club it seems the new plastics are still no good.

Could it be that one (or multiple) composite molds has worn out during all these years of producing?
Just an idea...

Brand new car, best electronics on the market installed, expert build, but shock plastics disappoint me.
