Summaries from the steering gear

Hello, with my wonderful Cabriolet C70 T5 (2001) I have to go to the workshop next week like every 10,000 km. I couldn’t drive from today by car anymore and that’s as soon as I take a strong turn, the well-known crackling noises come (will be lubricated in the workshop), but above all, and that’s why I leave this message, get a buzz or hum, which becomes stronger and less strong, but doesn’t go away. I’ve already been looked up on the road, I think that the noise is clearly audible from the outside. Who knows this problem ?
