rampage mt v3 alloy arm

just wanted to know why is there a hole on the arm like a grub screw goes into it where the pin goes what's that for and can i put a grub screw in there to help stop the pin from moving in and out from the vibration of the engine. and is there any kind of bushing that the rear hub carriers need to have in then where the pin goes so the wheel don't move left to right there's a little play in it there

the play is on the plastic rear hubs too
