Steering

Hello dear V8'ler,

for some time now a clear, short crack in the direction. In fact, at the right-hand impact, about the steering wheel lock.
I have not been so interested in this until today, because my fatter has other peoblemchen and which are more important to me. yesterday evening, however, at a lower speed and a right-hand hit, he was buzzing like a truck/bus braking. Can anyone give me a tip what's suspect?

Thank you for your help!

many greetings
Jürgen
