Axis problem

There’s something going majorly wrong with my axis in game, one example is when i make wheels using the wheels tool and go round a corner they totally spazz out! another is when i use wheels to make turret’s rotate it seems to invert the axis…

I believe it may only be for vertical axis only, horizontal seems to be fine.

And help would be greatly appreciated, seeing as this is totally ruining my gaming experience

Another example: http://wiki.garrysmod.com/?title=3D_tracking_turret

I followed that tutorial over and over but the wheels won’t ever stop moving, the horizontal axis seems to be capable of actually aiming the way the target is located, but still the y axis just spazzes out!!!

Please help!
