In this video I walk through how I diagnose a Fox 36 Rhythm that isn’t behaving like it should—and how I “rescue” it without guessing or copying some generic chart. The whole point is to figure out what the fork is actually doing on the trail, then narrow it down to what’s happening inside the damper and air spring. I’m focused on practical checks you can do to confirm the problem before you start throwing parts at it. I also cover the tool side of this, because suspension diagnostics and service get sketchy fast when you’re using the wrong stuff. I show the Fox tool setup I use for basically everything in this workflow, and I call out shaft clamps specifically—because if you’re going to open dampers, you need to hold shafts correctly without destroying them. If you want the “easy mode” version for a Fox 38, I link that too, but this one is about the mindset: test, observe, isolate, then fix what’s actually wrong.
