i have a similar sound, but mine is definitely the front piston. Mine has been doing it forever. If you disconnect the swaybar the sound will go away. It's a pain in the ass, but I'm probably going to remedy it buy going long travel and removing the front sway bar completely.
Some times look good with the lettering facing out. I know the BFG KO2s are powder blue from the beginning. They fade over time...
You could always do decals hahaha:
