47 rear hub pulling

[Bruce Lancaster]

Pulling from the studs is risky because of Ford's large bolt circle. You can bend the hub and drum sometimes without removing the thing.
Plomb and Snap on, the 2 main professional tool suppliers in the Flathead era, both supplied the hub stud type pullers...and both equipped them with special extra arms to allow them to pull from the central hub grooves on Fords.
