Replying to Skiing without AFD (Anti Friction Device) on binding

On my Marker Griffons one of the AFDs (sliders) broke off the toepiece. Apparently it's impossible to replace the AFD on a Marker Griffon binding, because you can't take the pin out which keeps the binding together, which is necessary to replace the AFD.

When you make sure the binding without AFD is the same height as it would be with the AFD, does it really make a big impact on the functionality of the binding, or is it still good to ski?

I'm not sure the warranty would cover this, and even if it would it will take ages..
