Hi. Where did you purchase your Fox shocks? Two of us so far with the same issue purchased from accutune. Fox didn’t want to throw them under the bus, but he speculated that it could be parts cleaner that wasn't cleaned out. Did you open your adjusters to look for damage? See my comments on your post. The steel balls were covered in white chalky material which is actually eroded aluminum.
It has been a while, but if I recall it was poly performance. They have been super helpful on other aspects, but not with the Fox shocks. I'm just going to blow these out and get something else
