Hey yoohoo, for Ernestos sake (so he can make my hell cats!), bring them over to my place in northpark. I have the correct circlip pliers. You just need to find the proper lithium (right?) grease to regrease them.
If you want to take a stab at battle hardening them, I have glass microspheres. Find the epoxy you want and I can help you do it.
Emphasis on “help”.
