Re: Spring shackle stud
What do you mean by one piece? I wouldn't call them that, but not really clear what your referring to.

Re: Spring shackle stud
No idea how you can call them one piece, must be a different definition than what I am familiar with. They are made of several pieces, a core, a center material and an outer shell. If you are referring to just the center core, it would be one piece end to end. Still not sure what the actual question is?

Re: Spring shackle stud
""JSeery states:made of a core, a center material and an outer shell.""
The Ford parts book calls this; Stud- spring shackle So,the outer shell is pressed into the spring or perch eye and the core is captured by the shackle bar. The center material enables the core to rotate slightly when the spring flexes. Is that how it works ??? |

Re: Spring shackle stud
Yes.Mine were shot .When I drove out the spring shackle stud (in my pic) that is what came out.I then drove out the outer shell with a banged up socket.The stud is or at least in my case ,was vulcanized.I replaced both sides with the ones Speedway sells.

Re: Spring shackle stud
Originals are as described, the center part that turns is wrapped in what looks like asbestos webbing. The ends of the outer shell are crimped and the whole thing is installed as 1. I have done this using home made tools (in a lathe) but since have acquired a KRW tool to remove and replace these things. It is MUCH easier with the KRW tool but removing the old rusted ones can still be a battle. I usually run a brake hone in the bore before installing new shackle pins. You might throw them in the freezer overnight to help with the task of installing them if you don't have the KRW tool.
On my 40s, I notice that the 2 that hold the front sway bar does not have cotter pin holes like the ones for the springs and uses a special nut. |

Please be aware that many guys reduce the outer (shell) diameter to more easily install these pins. Doing so is akin to replacing a worn out "old" pin with a worn out "new" pin. These pins were deigned to be oversize. As I recall, .003" - .004" was the specified "over size".

Re: Spring shackle stud
When I disassemble my axles should I leave the shackle studs intact if they are tight ???

I suppose you could put a wrench over the flats of each stud and attempt to turn it. If the stud turns at all, the pin is worn out. And I mean with you really TRYING to turn it...
