Hi Chris,
You are correct you will need a puller, each section holds a set of tools and everything you need to safely remove the front brake drums. I would suggest you remove both drums as the problem could well be on the left side, brake fluid on the shoes can cause the brakes to snatch. When refitting the drums the tappers on the drive shafts and the drum tappers must be spotless and free from oil or grease. It is then vital that the nuts are tightened to the correct torque, you will need a large torque wrench. Plenty of information in the magazine on this subject. Don’t forget the the right hand side hub nut should be a left hand thread. I say should be as I have come across incorrect fitment of driveshafts in the past.
If you look in the magazine you will find your local section coordinator, if the tools are not out on loan you can collect them and do the job.
The very best of luck.
