Question about leaf spring suspension

[Tom Kirkham]

You need thrust washers.

Thank you Tom....This brings up another question or 2. Does the outer ends of the pins get a thrust washer and then a regulat washer before the nut goes on? Also the other end where the shock mounts. What goes on there?

Anyone have a good picture of an original setup?

Thanks Mark

The questions I ask in the post before this one is for the reasoning. The pin is clamped into the upright and therefore rotate a small amount. So the part of the pin that goes thru the shock bushing rotates a small amount.

Been thinking about it some more. On the ends maybe the washers and nuts on the ends of the pin never touch the control arm on the ends by the seals. As you can see I am confused.

The original thrust washers were GARLOCK BEARINGS, INC. G10DU.

There were also four each seals as AC Cars intended that the bushes to last for years without further service.

Original pivot pins have a step down for the shock absorber mount on the forward facing end. The shafts were precision and chromium plated. For repairs I bought hydraulic cylinder shaft material that is very robust and had the parts cut from them. Special washers and thin Aerotight® nuts went on both ends.

Morris Thanks for the pictures. Although A little different than what I am doing I still like to learn. I probably like these kind of pictures a lot more than a picture of a cobra at a car show. I like to know what makes things tick!

Thanks again Dan. Don't know what I was thinking when I said shock mount. So yes I should of said sway bar mount. From what you posted things are starting to make sense.

So I now assume the upper rubber bush on the shock has an inner sleeve. Is this correct?

From what my drawings show it looks like the 3/4 dia part of the pin is 6.375. Also the part of the control arm that this pin goes thru to the outside edges is also 6.375 . So if these parts are the exact length the special washers would just be touching the ends of the control arm. Is this correct or should there be a little clearance there so it is not steel on steel contact?

Looking under a car yesterday, it looks like just enough clearance to not drag.
