XRAY - Model racing cars

Since I bought mu xb8tq used and I dont really know how much play there is on some parts on the buggy, I would like some help in order to figure out if I have to replace any parts.

I noticed that the rear pivot balls that goes in the rear upper camber link have a slight play when moving them back and forth and side to side. is this normal?

also the is a small play where the screw is that goes into the c-hubs and the steering blocks.

and finally there is also some play where the pivot ball goes into the servo ball joint that is attached on the servo saver. Although the play is very small at that place when trying to see ihow much play there is at the wheels the play is obviously more.
