V70 tires at the front left (saw tooth)! Axle measurement; shock absorber change

Hello Volvo-Freaks, my V70 BJ. 2005 – 70,000 km makes terrible rolling noises. The master of my trust has told me that the dampers are through and therefore the tires outside the front have developed to the saw tooth. What is necessary now? – An axle measurement and to direct the fall? – new tires? – new dampers? or everything? For experiences of yours or recommendations I would be very grateful to you!! Greetings MC
