A guarantee question – your opinion !?

Hello, wanted to have your opinion on a warranty question! I asked a few times about a crackling noise on the front axle. As you mentioned, a Volvo dealer confirmed to me that it was the cathedral warehouse. Although the dealer said that it was not relevant for safety reasons, it is still on my nerves, which is why I would like to have the problem solved. Since we bought the car only 6 months ago, I hoped to get the repair on guarantee. First I asked Volvo directly. However, these rejected any culling performance (only 2 years warranty). Also the car guarantee concluded with the purchase rejected a reperatur, since the component is not mentioned in the contract. However, I am still of the opinion that there is a warranty case and therefore directly asked the dealer where we bought the car. Here I am waiting for a call back. How can you see this? Can I assert warranty claims? If the dealer refuses to take legal action, then the free reperature (legal protection insurance for me).
