How would i go making about making Steering with hinges not flop around while not steering?

I have my custom chassis (which is basic) finished BUT the steering flops around while driving because the servo still acts as a hinge so i need it keep it from moving because i have the steering and wheels separate and i need to freeze the steering

could you provide images of the problem?
