It's easy but Home Depot is not the place to go. Most flaps/Napa have the studs. Probably 7/16-20. At the length you need. On the bench, press or knock out the old and install the new. Search and read 6-8 different blogs/how-to's. Use a bunch of washers and a backward lug nut to draw the stud in.
Don't listen to folks saying that method won't work. The Internet has it done with washers and backward nut on Hemmings, Autozone, and a billion other places. Millions of lug bolt changes with NO problem. Pressing them in is also a good way. Pressing them out and pressing them in, has to be done with proper, strong, backing.
