I have a 1940 Sedan. How do you know if the spring shackles need to be replaced? Are there warning signs?

When the threaded stud in the center has worn through the insulation and is wearing on the steel housing that encases it.

37RAGTOPMAN, I will take a couple of photos and post them sir. 3w2, "When the threaded stud in the center has worn through the insulation and is wearing on the steel housing that encases it." How would I see this with the shackle assembled? Do I need to remove one of the two, sheet metal plates/links? Thank you both!

There is usually enough room to see between the shackle plate and the hanger on the wishbone to see the wear. Another way to tell is put a jack under the spring and gently lift the spring and look for up and down movement of the shackle stud in the wishbone.

As trjford8 indicates, you perhaps can see the wear behind the figure 8 end plates or notice that the end plate seems off center with the shape of the spring eye or spring perch if the wear is advanced. Otherwise, yes, you can back off the retaining nuts on the studs enough to create some space to have a better view short of removing the figure 8 end plates. If you remove one of them you likely will need a spring spreader to reinstall it.

I believe that years ago they made a tool, it was like a fork with 2 ends that would grip the spring and you would try moving the spring to see if it had any play it was much like a tie-rod fork, the tie rod fork might also work, my 2 cents, 37Ragtopman
