Modifications were made along the way from a multitude of sources, either to what fit, or what was on hand. Junk yard builds are the norm on these Heeps.
You didn't need a puller to remove the drum because it had already had been removed previously. On most old Jeeps, the wheel studs are swedged to the drum, (material peened in against the stud on the drum). The drum is then essentially one piece with the hub. With the center nut removed, then the entire hub would most often have to be pulled off with the puller. If you had to replace the drums or studs, then you had to use a swedge cutter to remove the material that had been peened against the stud. This step is rarely done when installing new drums or studs because it was really overkill, as long as you torqued the lug nuts to prevent them from working loose.
