I made a puller by turing an old break rotor around and using a the type of puller that has 3 fingers with slots. I put the old rotor over the studs for the lug nuts and then bolted the puller to 3 of the studs with the lug nuts and then screwed in the puller screw bolt to the center of the axel. I think this is better than a gear puller if you have an old rotor. If you loosen the 36 mm hex nut before you jack the car off of the ground it is easier....you don;t need a second person to push on the brakes. good luck.
