2021 Blazer

I went for my first oil change and found out that the boot on the drivers' side axel is cracked, causing it to leak axle grease. The dealership has to replace the entire axle. The dealer told me that because the car is so new, they haven't stocked the warehouses with the parts to fix it, waiting for them to find a part to have it shipped to the dealer for repair.

Brakes have been squeaking since day one, I have been to the dealer, and they told me it is normal for new brakes to squeak, but today I noticed that even when not pushing the brake pedal, the wheel was squeaking with every rotation. (Maybe due to the cracked axle boot?).
