So boredom or curiosity or what ever you want to call it strikes again and I wanted to figure out a way to confirm that I have a bent axle shaft. So I knew it was bent when it was on the car because you could see the wheel move in and out about 1/4 of an inch when spinning but I didn't know if it was the shaft or the hub or both.
Take a piece of wood, some cabinet rollers and a scrap metal plate and make a jig for axle shafts to check the tolerances of the hub and the shaft, that is if you already have a dial indicator.
So here it is, now granted there is some play in it, but it works well enough to tell if you have a bent axle shaft or hub and I got some fairly good measurements on the one I thought was bent.
As it turns out, my good axles there is about 10 thousands of inch variance in the hub on the vertical per one revolution and less than that on the shaft measuring in two spots to get an idea of variance over the length.
The one I thought was bad as it turns out, has both issues, about 25 thousands of an inch variance in the hub on the vertical per one revolution, and around 40 thousands inch variance in the shaft over the distance of about 12 inches. The variance in the axle shaft actually is visibly noticeable when its rotated in the jig when using the dial mount as a reference.
Anyways, thought I would share!
