Question about leaf spring suspension

[Dan Case]

Thank you Dan! I have the bushings and seal. I need to make the plate with the 3 inch hole in it and the shock mount to finish the rear lower a arms.

DC: Do you mean stabilizer bar link mount? The lower dampener mount is the forward end of the shaft the lower end of the vertical link pivots on.



When I am done with that my next project is to make the pins. By the drawings I got it looks like the part of the pin that is 3/4 is the same overall length as the overall width of the a arm where it connects. I plan on using the same material as you stated.

Could you tell me does the end of the pin that just get the special washer and the nut. Does the washer come into contact with the a arm? Also on the shock end. Does the rubber bushing in the lower end of the shock come in direct contact with the A arm? Or does it get a washer put on first? Also does the rear shocks have steel sleeve inside the rubber bushings.

DC: Whew, bunches of questions. It has been a few years since I had all the rear suspension off and apart but from pin drawings and memory:

• face to face on the 0.750” chromium plated working length section I came up with was nominally 6.375”. I have never reverse engineered the vertical links into drawings so I don’t know what their nominal width was.

• from what I recall there are three special washers

- At rear over the 7/16 BSF threaded stub end between the vertical link and the Aerotight® “thin” stop nut.

- Near the front over the shank of the lower dampener mount between the dampener rubber bush and the vertical link

- At the front between the front end Aerotight stop nut and the dampener rubber bush.

• None of the Armstrong® dampeners that I have held have a steel sleeve in the lower mount bushes.
