I have replaced both the front ands rears on my XC60.

Genuine Volvo pads include a guide on the correct procedure.

For the fronts I had to buy a 9 mm hex Alan key socket, the instructions said either 7 or 9 so you will need to check before you start and if you have the electric handbrake you will need a torx bit to wind back the motor.

Buy the pads first and see what instructions you get.
