ill agree with the last guy in my old shop when a car came in with a broken stud and the customer wanted it fixed we just removed the drum used a center punch and a good hammer knocked the old one out put some grease in the teeth on the hub slid the new one in lined up the teeth got a flat nut and some washers and used an impact gun on low and pulled them threw never had any problems just that the nut i used would get a lil banged up but i had tons at my disposal. if you dont have an impact gun use a long torque wrence or something of that nature lock the other wheel and put the car in gear(if its stick) that way the hub does not spin on you as you torque it down if its an auto that dont worry. as far as drums go when putting the drum on you want to adjust the shoes as far out as they can go but if you go too much the drum will not go back on so you'll have to back off a lil make it so that they are out far but the drum still fits that way your parking brake is tight and you'll have a high brake pedal(if you do both sides) your parking brake should only click 4x before it gets hard. i hope that helps any other questions let me know i have tons of answers regarding that kinda stuff good luck.
