Please take a look at this. It is a shim I removed from a wrecked truck about 40 years ago. There were 2 but one was lost along the way. Obviously it was homemade. It is tapered (which you can't really tell from this image) and was installed under the stock shim. There was no contact between the spring pin and the axle with this shim installed. Whether axle movement caused the wreck or contributed to it is an egg I couldn't unscramble because there was very little of the truck left, but in order to always remind myself of this situation, this has been in one of my tool boxes since then. I'm fairly certain the driver didn't survive. Or if he did it was a miracle.
