Axels on 2005 Acura

Hi, does it sound likely that the front axels on a 2005 Acura TL 40K miles would need replacing? And, my dealer wants to charge $975. I hear a cranking when I turn sharply at a low speed, like when parking.

Also, they want to charge me $375 for one of the motors on one of the windows, it doesn't always go back up, I have to play with the button.

Front brake pads on a manual transmission should go every 20K miles?

Thanks so much!
