Does anyone know this tool. It is in a snapon box bit I cannot find a name on the tool.

Thanks,

Probably the trunnion pin set, same page, for doing U-joints. needs only the threaded head and a cup (which you have), so would fit in a smaller box....

Thanks Guys

Agree with FrankLee, it is for King pins and perch pins, sure made life easy pushing out frozen king pins, I always used a torch, big punch and 5lb hammer or Zip gun.
