Crack at Left Curve

Hello dear Fox community, I have a Fox 1.4 (year 2005) with 70,000 km. I now have the following problem: Every time I turn left it makes one or two times “cracking”. What could not be okay there? It’s definitely not normal after 70,000 km, isn’t it? Besides, I have another problem: If I drive fast through a right turn, then there’s such a grinding noise from behind. It’s the same noise that comes when braking with slightly rusted brakes from both sides. mt (which is also normal when braking – only it comes without me braking when I quickly drive a right turn). Can you say something about it? Then I’m not quite so clueless in the workshop… Thank you so much Fox 1,4
