Chain ball problem

Hi guys, i am working on a car game where the car is dragging from the rear a chain with an iron ball attached to its end (the car grabs the chain using physics handle)…the player car should swing the chain to smash enemies with the ball. the chain ball is a separate physics object made of constraints to limit the movement of the chain and physics bodies to add collision, dampness,…etc…the problem is when you move the car and there are enemies moving around you or at the moment the ball hit something with high velocity, the ball will jerk and twitch a bit…you know like the ball shift its position fast and it seems like a broken movement…can anyone help? i dont know if it is processing or physics calculation issue or maybe something else?
