Losi Mini 8ight Sloppy Steering

[Twiglet]

Hi,
I have recently got my hands on a Losi mini 8ight, however after my first club night I have noticed that I am not getting the same amount of travel from the steering when turning left or right. On further investigation I seem to have quite a lot of play in the steering system. I have traced this to the second steering post (not the one attached to the servo). Anybody got any fixes, hop up parts to cure this, etc. I have changed the stock servo for a Hitec 5245MG.
Many thanks
Mark
