So I spent way too much time today trying to get the thru-axle on my Fox 40 to unscrew. Of course I totally stripped out the 5mm hex. That goes without saying. Even though I had completely removed all four pinch bolts, removed the little flat steel slit shim, and pried the jaws open a couple of millimeters with a flat blade screw driver. Anyhow, I finally got the m-effer (I rarely use foul language, but this was a cast iron bewitch) to unscrew by hammering a Torx bit into the ruined stripped 5mm hex hole and getting it loose with an impact driver, (NOT an impact gun, so you know).
Anyhow, there was evidence of a speck of grit, and a line of thread damage on the axle that probably coincides with the slit...
Anyway, I'm wanting to avoid this scenario again in the future. But I'm not sure how, other than to be surgically clean about re assembly.
Any other tips? And since I bought my bike used... is the Fox 40 supposed to have those slit shims? It's an air spring version, not the older coil spring version. Guessing around 2016-2018.
