anyone know the size of the drum retaining nut for the parking brake on a 1974 fj40 located behind the propellar shaft? I was told it was a large 24mm? is this correct? will I need a socket to get to it, or just an adjustable wrench. I have that well documented issue of oil leaking from the transfer case into the parking brake unit, so I have no parking brakes. any tips/hints on fixing this? I ordered one of those kits that contains all that is needed to fix the issues (brake shoes, seals, clips, dust cover, etc.). but wonder if I anything I should know. I was going to just park it on my driveway facing downhill, chock the wheels, and this way I do not have to drain transfer case. then, do the repair.
